为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步地详细描述。为了便于对本发明实施例的理解,下面首先介绍本发明实施例涉及的应用场景、以及所涉及到名词的概念。The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. In order to facilitate the understanding of the embodiments of the present invention, the application scenarios involved in the embodiments of the present invention and the concepts related to the nouns are first introduced.
本发明实施例中提供了一种光波导装置,可以应用于光传送网络中,作为光传输通路中的传输节点设备,如光波导装置可以是波长选择开关、光交换矩阵(或光开关阵列)设备等。In the embodiment of the present invention, an optical waveguide device is provided, which can be applied to an optical transmission network as a transmission node device in an optical transmission path, such as an optical waveguide device, which may be a wavelength selective switch, an optical switching matrix (or an optical switch array). Equipment, etc.
光波导,引导光信号在其中传播的介质结构,或者说是将光波(或光信号)限制在特定介质内部或其表面附近进行传输的导光通道。该介质可以是后面提到的光学材料等,具体有硅、氧化硅、液晶等。An optical waveguide that directs a dielectric structure in which an optical signal propagates, or a light guiding channel that confines light waves (or optical signals) within or near a particular medium for transmission. The medium may be an optical material or the like mentioned later, and specifically, silicon, silicon oxide, liquid crystal, or the like.
单个光信号,单个光信号是数据调制在一定的频率分量上的光信号,只有将这些频率分量都完成接收才能完整恢复出数据。A single optical signal, a single optical signal is an optical signal modulated by data on a certain frequency component, and only when these frequency components are received can the data be completely recovered.
单波光信号,单个光信号中的一种,只是单波光信号有一个中心波长。A single-wave optical signal, one of a single optical signal, except that the single-wave optical signal has a center wavelength.
合成光信号,包含多个频率分量不同的单个光信号。A composite optical signal comprising a plurality of individual optical signals having different frequency components.
合波光信号,包含多个频率分量不同的单波光信号。这也就是说,合波光信号中的单波光信号有不同的中心波长。A multiplexed optical signal comprising a plurality of single-wave optical signals having different frequency components. That is to say, the single-wave optical signals in the combined optical signal have different center wavelengths.
可变光波导,基于配置信息控制光学材料形成光信号通路或者消除光信号通路实现对 应的光处理功能的部件。也即,可变光波导可以基于配置信息调整光波导单元可以实现的光处理功能或者光处理功能对应的性能。具体是:基于配置信息控制光学材料形成可以用于传输光信号的光信号通路、或者消除已有的用于传输光信号的光信号通路。形成用于传输光信号的光信号通路可以包括两种情况,一种是在没有用于传输光信号的光信号通路的基础上,形成光信号通路,另一种是在已有的用于传输光信号的光信号通路的基础上,改变用于传输光信号的光信号通路的形状。基于配置信息控制光学材料的方式有多种。例如,光学材料是液晶,采用点阵式电极,光学材料的每个区域都对应有点阵式电极,用于控制光学材料的折射率,配置信息中包括对应点阵式电极的加电压方式和/或哪些电极需要改变电压等,在光学材料的预设区域对应的点阵式电极加相应的电压(或者不加相应的电压,加或者不加电压,取决于液晶材料的类型),使该预设区域的折射率大于光学材料的其它区域的折射率,从而可以在预设区域形成光信号通路。The variable optical waveguide controls the optical material to form an optical signal path based on the configuration information or eliminates the optical signal path to implement a corresponding light processing function. That is, the variable optical waveguide can adjust the performance corresponding to the light processing function or the light processing function that the optical waveguide unit can implement based on the configuration information. Specifically, the optical material is controlled based on the configuration information to form an optical signal path that can be used to transmit the optical signal, or to eliminate an existing optical signal path for transmitting the optical signal. Forming an optical signal path for transmitting an optical signal may include two cases, one is to form an optical signal path on the basis of no optical signal path for transmitting the optical signal, and the other is to be used for transmission. Based on the optical signal path of the optical signal, the shape of the optical signal path for transmitting the optical signal is changed. There are many ways to control optical materials based on configuration information. For example, the optical material is a liquid crystal, and a dot matrix electrode is used. Each region of the optical material corresponds to a dot array electrode for controlling the refractive index of the optical material, and the configuration information includes a voltage application method corresponding to the dot matrix electrode and/or Or which electrodes need to change the voltage, etc., in the preset area of the optical material corresponding to the dot matrix electrode plus the corresponding voltage (or no corresponding voltage, plus or no voltage, depending on the type of liquid crystal material), so that the It is assumed that the refractive index of the region is greater than the refractive index of other regions of the optical material, so that an optical signal path can be formed in the predetermined region.
固定光波导,与可变光波导相对应,是预设的光信号通路不能更改的光波导,也即固定光波导制作完成后,预设的光信号通路也都制作完成,在后续一般不能更改。预设的光信号通路是指预先设置的、有成为光信号通路前提条件(或可以成为光信号通路)的通路,一旦往该通路输入光信号就成为光信号通路,如果没有往该通路输入光信号,该通路还不能称为准确意义上的光信号通路。这样,在通常情况下,固定光波导实现的光处理功能不能改变。一般地,在制作完成后,固定光波导实现的光处理功能对应的性能也不能改变。The fixed optical waveguide, corresponding to the variable optical waveguide, is an optical waveguide whose preset optical signal path cannot be changed, that is, after the fixed optical waveguide is completed, the preset optical signal path is also completed, and cannot be changed in the following. . The preset optical signal path refers to a path that is pre-established and becomes a precondition (or can be an optical signal path) of the optical signal path. Once the optical signal is input to the path, it becomes an optical signal path, and if no light is input to the path, Signal, this path cannot be called an optical signal path in the exact sense. Thus, under normal circumstances, the light processing function implemented by the fixed optical waveguide cannot be changed. Generally, the performance corresponding to the light processing function implemented by the fixed optical waveguide cannot be changed after the fabrication is completed.

The configuration information includes a voltage application method corresponding to the dot matrix electrode and/or which electrodes need to change the voltage, and the dot matrix electrode corresponding to the predetermined region of the optical material is added. The voltage (or without the corresponding voltage, with or without voltage depending on the type of liquid crystal material), causes the refractive index of the predetermined region to be greater than the refractive index of other regions of the optical material, thereby forming an optical signal in a predetermined region path.

The optical signal between the seventh interface point 27 and the optical fiber is transmitted to the optical fiber, or the optical signal between the interface point corresponding to the optical fiber through the seventh interface point 27 is transmitted to the optical fiber for output.
需要说明的是,上述提到的“一个功能单元2”和“N个功能单元2”是特指,也就是说“一个功能单元2”用于进行光信号的分离,“N个功能单元2”用于进行光信号的合成。It should be noted that the above-mentioned "one functional unit 2" and "N functional unit 2" are specifically referred to, that is, "one functional unit 2" is used for separation of optical signals, "N functional units 2 "Used for the synthesis of optical signals.
同样,如图6(b)所示,第七接口点27为合成光信号接口点,第八接口点28为单个光信号接口点,光波导装置也可以为N*1的WSS,当光波导装置为N*1的WSS时,相当于有N个功能单元2中每个功能单元2用于将一路合成光信号分为多路单个光信号,传输至一个功能单元2,该一个功能单元2将接收到的多路单个光信号进行合成,得到一路合成光信号,进行输出。Similarly, as shown in FIG. 6(b), the seventh interface point 27 is a composite optical signal interface point, the eighth interface point 28 is a single optical signal interface point, and the optical waveguide device can also be an N*1 WSS, when the optical waveguide When the device is N*1 WSS, each of the N functional units 2 is used to divide one combined optical signal into multiple single optical signals and transmit to a functional unit 2, the one functional unit 2 The received multiple optical signals are combined to obtain one combined optical signal for output.
每个功能单元2包括一个第七接口点27和多个第八接口点28,光波导单元1可以基于配置信息,生成或改变电场、磁场、温度等来控制光学材料连接光纤与第七接口点27,形成光纤与第七接口点27之间的光信号通路,或者,基于配置信息,生成或改变电场、磁场、温度等来控制光学材料连接光纤对应的接口点与第七接口点27,形成光纤对应的接口点与第七接口点27之间的光信号通路。Each functional unit 2 includes a seventh interface point 27 and a plurality of eighth interface points 28, and the optical waveguide unit 1 can generate or change an electric field, a magnetic field, a temperature, etc. based on the configuration information to control the optical material connecting fiber and the seventh interface point. 27, forming an optical signal path between the optical fiber and the seventh interface point 27, or generating or changing an electric field, a magnetic field, a temperature, etc. based on the configuration information to control an interface point corresponding to the optical material connecting the optical fiber and the seventh interface point 27, forming The optical signal path between the interface point corresponding to the optical fiber and the seventh interface point 27.
当多路光信号分别通过光波导单元1建立的光纤与N个第七接口点27之间的光信号通路传输至N个第七接口点27,或者通过光波导单元1建立的光纤对应的接口点与N个第七接口点27之间的光信号通路传输至N个第七接口点27,N个第七接口点27分别所属的N个功能单元2可以将接到的光信号按照频率分量进行分离,得到多路单个光信号,分别通过与一个功能单元2的第八接口点28之间的光信号通路,传输至该一个功能单元2的第八接口点28,该一个功能单元2将第八接口点28接收到的多路单个光信号,合成一路包含多个不同频率分量的光信号(即一路合成光信号),送往该一个功能单元2的第七接口点27,通过第七接口点27与光纤之间的光信号通路传输至光纤,或者通过第七接口点27与光纤对应的接口点之间的光信号传输至光纤,进行输出。When the multi-path optical signals are respectively transmitted through the optical signal path between the optical fiber established by the optical waveguide unit 1 and the N seventh interface points 27, to the N seventh interface points 27, or the interfaces corresponding to the optical fibers established by the optical waveguide unit 1 The optical signal path between the point and the N seventh interface points 27 is transmitted to the N seventh interface points 27, and the N functional units 2 to which the N seventh interface points 27 respectively belong can receive the received optical signals according to the frequency components.

需要说明的是,上述提到的“一个功能单元2”和“N个功能单元2”是特指,也就是说“一个功能单元2”用于进行光信号的合成,“N个功能单元2”用于进行光信号的分离。It should be noted that the above-mentioned "one functional unit 2" and "N functional unit 2" are specifically referred to, that is, "one functional unit 2" is used for synthesizing optical signals, "N functional units 2 "Used for separation of optical signals.
如图6(c)所示,第七接口点27为合成光信号接口点,第八接口点28为单个光信号接口点,当光波导装置为S*T的WSS时,相当于有S个功能单元2中每个功能单元2用于将一路光信号分为多路不同频率分量的单个光信号,最终输出T路光信号。As shown in FIG. 6(c), the seventh interface point 27 is a composite optical signal interface point, and the eighth interface point 28 is a single optical signal interface point. When the optical waveguide device is S*T WSS, it corresponds to S. Each functional unit 2 in the functional unit 2 is used to divide one optical signal into a single optical signal of multiple different frequency components, and finally output a T optical signal.
光波导单元1可以基于配置信息,生成或改变电场、磁场、温度等来控制光学材料连接光纤与第七接口点27,形成光纤与第七接口点27之间的光信号通路,或者,基于配置信息,生成或改变电场、磁场、温度等来控制光学材料连接光纤对应的接口点与第七接口点27,形成光纤对应的接口点与第七接口点27之间的光信号通路。The optical waveguide unit 1 may generate or change an electric field, a magnetic field, a temperature, or the like based on the configuration information to control the optical material connecting fiber and the seventh interface point 27 to form an optical signal path between the optical fiber and the seventh interface point 27, or based on the configuration. The information, the electric field, the magnetic field, the temperature, and the like are generated or changed to control the interface point corresponding to the optical material connecting the optical fiber and the seventh interface point 27 to form an optical signal path between the interface point corresponding to the optical fiber and the seventh interface point 27.
当一路合成光信号通过光波导单元1建立的光纤与第七接口点27之间的光信号通路传输至该第七接口点27,或者通过光波导单元1建立的光纤对应的接口点与第七接口点27之间的光信号通路传输至该第七接口点27,该第七接口点27所属的功能单元2可以将接到的合成光信号按照频率分量进行分离,得到多路单个光信号,分别送往自己的一个第八接口点28,或者将得到的多路单个光信号中,某几路单个光信号传输至一个第八接口点28。然后通过第八接口点28与光纤或光纤对应的接口点之间的光信号通路发送至光纤,进行输出。When the optical signal path between the optical fiber established by the optical waveguide unit 1 and the seventh interface point 27 is transmitted to the seventh interface point 27, or the optical fiber waveguide unit 1 establishes an interface point corresponding to the optical fiber and the seventh The optical signal path between the interface points 27 is transmitted to the seventh interface point 27, and the functional unit 2 to which the seventh interface point 27 belongs can separate the received composite optical signal according to the frequency component to obtain a plurality of single optical signals. They are sent to their own eighth interface point 28, or some of the obtained multiple optical signals are transmitted to an eighth interface point 28. Then, the optical signal path between the interface point corresponding to the optical fiber or the optical fiber through the eighth interface point 28 is sent to the optical fiber for output.
在上述1*N的WSS、N*1的WSS和S*T的WSS中,都是基于第七接口点27为合成光信号接口点,第八接口点28为单个光信号接口点描述的,如果第七接口点27为合波信号接口点,第八接口点28为单波光信号接口点,与上述对光波导装置的描述基本相同,只要将上述描述中的“合成光信号”替换为“合波光信号”,“单个光信号”替换为“单波光信号”即可,其余过程完全相同。In the above 1*N WSS, N*1 WSS and S*T WSS, the seventh interface point 27 is based on the composite optical signal interface point, and the eighth interface point 28 is described as a single optical signal interface point. If the seventh interface point 27 is a multiplexed signal interface point, the eighth interface point 28 is a single-wave optical signal interface point, which is substantially the same as described above for the optical waveguide device, as long as the "composite optical signal" in the above description is replaced with " The multiplexed optical signal", "single optical signal" can be replaced by "single-wave optical signal", and the rest of the process is identical.
可选的,光波导装置为WSS时,为了节约光信号在光波导单元1中的传输路径,功能单元2可以通过第二可变光波导实现,相应的处理可以如下:Optionally, when the optical waveguide device is WSS, in order to save the transmission path of the optical signal in the optical waveguide unit 1, the functional unit 2 can be implemented by the second variable optical waveguide, and the corresponding processing can be as follows:
如图7所示,功能单元2通过第二可变光波导实现时,相当于光波导单元1和功能单元2都是通过可变光波导实现,只不过光波导单元1是通过第一可变光波导实现,第二可变光波导的光滑程度高于第一可变光波导,或者,第二可变光波导的单位长度损耗低于第一可变光波导(他们之间的区别已经在前面详细叙述,此处不再赘述)。具体实施时,第一可变光波导1和第二可变光波导1可以采用相同的液晶材料,但第二可变光波导1对应的点阵式电极密集程度高于第一可变光波导1对应的点阵式电极密集程度。As shown in FIG. 7, when the functional unit 2 is implemented by the second variable optical waveguide, both the optical waveguide unit 1 and the functional unit 2 are realized by the variable optical waveguide, except that the optical waveguide unit 1 is passed through the first variable. The optical waveguide realizes that the second variable optical waveguide is smoother than the first variable optical waveguide, or the second variable optical waveguide has a lower unit loss than the first variable optical waveguide (the difference between them is already As detailed above, it will not be repeated here.) In a specific implementation, the first variable optical waveguide 1 and the second variable optical waveguide 1 may use the same liquid crystal material, but the second variable optical waveguide 1 corresponds to a dot matrix electrode denser than the first variable optical waveguide. 1 corresponds to the intensity of the dot matrix electrode.
功能单元2的数目大于或等于2,功能单元2包括一个第十五接口点215和多个第十六接口点216,光波导单元1与光纤或光纤对应的接口点连接,光波导单元1可以基于配置信息,生成或改变电场、磁场、温度等来控制光学材料连接光纤与第十五接口点215,形成光纤与第十五接口点215之间的光信号通路,或者,基于配置信息,生成或改变电场、磁场、温度等来控制光学材料连接光纤对应的接口点与第十五接口点215,形成光纤对应的接口点与第十五接口点215之间的光信号通路。The number of the functional units 2 is greater than or equal to 2. The functional unit 2 includes a fifteenth interface point 215 and a plurality of sixteenth interface points 216. The optical waveguide unit 1 is connected to an interface point corresponding to an optical fiber or an optical fiber, and the optical waveguide unit 1 can be Generating or changing an electric field, a magnetic field, a temperature, etc. based on the configuration information to control the optical material connecting fiber and the fifteenth interface point 215 to form an optical signal path between the optical fiber and the fifteenth interface point 215, or generating based on the configuration information Or changing the electric field, the magnetic field, the temperature, etc. to control the interface point corresponding to the optical material connecting fiber and the fifteenth interface point 215, forming an optical signal path between the interface point corresponding to the optical fiber and the fifteenth interface point 215.
第十五接口点215为合成光信号节点,第十六接口点216为单个光信号接口点,当一路合成光信号通过光纤或光纤对应的接口点与第十五接口点215之间的光信号通路,传输至第十五接口点215时,该第十五接口点215所属的功能单元2可以将接收到的一路合成光信号按照频率分量,分为多路单个光信号,送往该功能单元2的第十六接口点216,通过该第十六接口点216与其它功能单元2的第十六接口点216之间的光信号通路,将多路单个光信号传输至其它功能单元2,其它功能单元2中每个功能单元2可以将通过第十六接口点216接收到的多路单个光信号进行合成,得到一路合成光信号,其它功能单元2中每个功能单元2可以通过第十五接口点215与光纤或光纤对应的接口点之间的光信号通路,将得到的一路合成光信号传输至光纤,进行输出。The fifteenth interface point 215 is a composite optical signal node, and the sixteenth interface point 216 is a single optical signal interface point. When one synthetic optical signal passes through an optical signal between an interface point corresponding to the optical fiber or the optical fiber and the fifteenth interface point 215, When the path is transmitted to the fifteenth interface point 215, the functional unit 2 to which the fifteenth interface point 215 belongs may divide the received combined optical signal into multiple single optical signals according to the frequency component, and send the signal to the functional unit. The sixteenth interface point 216 of the second optical signal is transmitted to the other functional unit 2 through the optical signal path between the sixteenth interface point 216 and the sixteenth interface point 216 of the other functional unit 2, and the other Each functional unit 2 in the functional unit 2 can synthesize the multiple single optical signals received through the sixteenth interface point 216 to obtain one combined optical signal, and each functional unit 2 in the other functional units 2 can pass the fifteenth The optical signal path between the interface point 215 and the interface point corresponding to the optical fiber or the optical fiber transmits the obtained combined optical signal to the optical fiber for output.
需要说明的是,由于光波导单元1和功能单元2都通过可变光波导实现,这样可以将功能单元2放在光波导单元1的中间,缩短光波导单元1和功能单元2的连接长度,节约光信号在光波导单元1中的传输路径。It should be noted that since both the optical waveguide unit 1 and the functional unit 2 are realized by the variable optical waveguide, the functional unit 2 can be placed in the middle of the optical waveguide unit 1 to shorten the connection length of the optical waveguide unit 1 and the functional unit 2. The transmission path of the optical signal in the optical waveguide unit 1 is saved.
需要说明的是,上述仅以光波导装置1*N的WSS为例进行说明,N*1的WSS、M*N的WSS和S*T的WSS与之类似,不再详细叙述。It should be noted that the WSS of the optical waveguide device 1*N is described as an example. The WSS of N*1, the WSS of M*N, and the WSS of S*T are similar, and will not be described in detail.
另外,第十五接口点215为合波光信号接口点、第十六接口点216为单波光信号接口点,与上述对光波导装置的描述基本相同,只要将上述描述中的“合成光信号”替换为“合波光信号”,“单个光信号”替换为“单波光信号”即可,其余过程完全相同。In addition, the fifteenth interface point 215 is a multiplexed optical signal interface point, and the sixteenth interface point 216 is a single-wave optical signal interface point, which is substantially the same as the above description of the optical waveguide device, as long as the "composite optical signal" in the above description is used. Replace with "combined optical signal", "single optical signal" is replaced by "single-wave optical signal", and the rest of the process is identical.
还需要说明的是,在上述介绍的两种光波导装置的结构中,光波导装置既可以是1*N的WSS、也可以是M*N的WSS、也可以是S*T的WSS,还可以是1*N的WSS,这样,可以解除WSS在光背板的应用限制,这是由于:It should be noted that, in the structure of the two types of optical waveguide devices described above, the optical waveguide device may be 1*N WSS, M*N WSS, or S*T WSS. It can be 1*N WSS, which can remove the application limit of WSS on the optical backplane, which is due to:
在现有技术中,1*N的WSS、N*1的WSS、M*N的WSS和S*T的WSS的制作方式都是不一样的,当一个WSS制作完成后,就确定了该WSS是1*N的WSS、N*1的WSS、M*N的WSS和S*T的WSS可以实现何种光处理功能,也就是说WSS的光处理功能已经固定。WSS一般是插在光背板设置的槽位上,由于光背板中,槽位之间的光纤连接是固定的,以及哪些槽位是连接接收机、发射机都是固定的,因此不同种类的WSS需要安装在固 定的槽位上,才能实现自己相应的光处理功能,例如,如图8所示,一共有9个槽位(简化了结构),最上面一排的三个槽位只能插1*N的WSS,而中间一排的前两个槽位只能插S*T的WSS,最下面的三个槽位和中间一排的最后一个槽位只能插N*1的WSS,但是在实际使用时,光传送网络中的节点设备的光背板连接的接收机和发射机有可能不相同,要连接的线路光纤的数量也不相同,因此需要连接的1*N的WSS和S*T的WSS的数量也是不相同的,由于1*N的WSS和S*T的WSS实现的光处理功能均不相同,那么在S*T的WSS的槽位不足时,即使1*N的WSS的槽位有空余,也不能用于安装S*T的WSS,需要增加光背板中的槽位,进而增加了构建光传送网络的成本。In the prior art, 1*N WSS, N*1 WSS, M*N WSS, and S*T WSS are all produced differently. When a WSS is completed, the WSS is determined. It is the light processing function of 1*N WSS, N*1 WSS, M*N WSS and S*T WSS, which means that the WSS light processing function has been fixed. WSS is usually inserted in the slot set on the optical backplane. Because the optical fiber connection between the slots is fixed in the optical backplane, and the slots are connected to the receiver and the transmitter is fixed, different types of WSS are used. You need to install it in a fixed slot to implement its own optical processing function. For example, as shown in Figure 8, there are a total of 9 slots (simplified structure), and the three slots in the top row can only be inserted. 1*N WSS, and the first two slots in the middle row can only be inserted into the S*T WSS. The bottom three slots and the last slot in the middle row can only be inserted into the N*1 WSS. However, in actual use, the receiver and transmitter of the optical backplane connected to the node equipment in the optical transmission network may be different, and the number of the optical fibers to be connected is also different, so the 1*N WSS and S to be connected are required. *T's WSS number is also different. Since the 1*N WSS and S*T WSS implement different light processing functions, then the S*T WSS slot is insufficient, even if 1*N The slot of the WSS is free, and it cannot be used to install the WSS of the S*T. You need to increase the slot in the optical backplane to increase the slot. Construction cost of the optical transport network.
然而本发明实施例中,在WSS的需求量小于预设总量的情况下,可以基于光背板的槽位配置信息,调整是生成S*T的WSS,还是生成1*N的WSS。从而不需要增加光背板的槽位,进而可以降低构建光传送网络的成本。In the embodiment of the present invention, if the required amount of the WSS is less than the preset total amount, the WSS of the S*T or the WSS of the 1*N may be generated based on the slot configuration information of the optical backplane. Therefore, it is not necessary to increase the slot of the optical backplane, thereby reducing the cost of constructing the optical transport network.
另外,现有技术中的WSS都是基于空间光学中的光学器件(如透镜、棱镜等)实现的,对震动要求比较高,实现难度大,然而本发明实施例中,是采用固定光波导和可变光波导来实现的,对震动的要求不高,可以降低WSS的实现难度。In addition, the WSS in the prior art is implemented based on optical devices (such as lenses, prisms, etc.) in the space optics, and the vibration requirements are relatively high, and the implementation is difficult. However, in the embodiment of the present invention, the fixed optical waveguide and the fixed optical waveguide are used. Variable optical waveguides are not required for vibration, which can reduce the difficulty of WSS implementation.
可选的,本发明实施例中,光波导装置既可以是1*N的WSS,也可以是光交换矩阵(或光开关阵列)设备,相应的结构可以如下:Optionally, in the embodiment of the present invention, the optical waveguide device may be either a 1*N WSS or an optical switching matrix (or optical switch array) device, and the corresponding structure may be as follows:
