In optical fiber network system, the transmission of information is that the transmission in optical fiber realizes by light signal.For information better being distributed/linking, we need light signal in the future to be transferred to respectively different circuits or the light of different circuits to be switched in the circuit of appointment.Conventional system for delivering is that the bi-directional conversion by photoelectricity/electric light realizes.But, in the process of transmitting at high-speed optical signal, the conversion of photoelectricity/electric light often becomes speed bottle-neck.And, for multichannel optical information transmission, the conversion of photoelectricity/electric light is very difficult, needs a lot of pre-service work.Therefore, although can realize easily when electric signal transmits in plain conductor connecting, and light signal will enter output optical fibre from input optical fibre and must have point-device lotus root to close, otherwise the loss of light intensity will be very serious.We still tend to realize the direct switching transmission of light signal.
According to principle of work and material therefor, photoswitch can be divided into mechanical type and the large class of on-mechanical formula two.The realization of non-mechanical optical switch is mainly to adopt the mode such as electrooptical effect to realize the switching of light signal, but, electrooptical effect is often with factor analysis such as wavelength, polarization, temperature, and this makes final device may have larger WDL, PDL, TDL etc., is unfavorable for actual use.

Embodiment 1: structure as shown in Figure 1, in the present embodiment, input-output system 101 is that three optical fiber, condenser lens 102 are microlens array, the output light of three optical fiber projects on rotary MEMS103 after microlens array focuses on, when need to export from upper port, MEMS will rotate and adjust catoptrical angle, make the lens of top in its incident microlens array, and the optical fiber cable that finally is coupled to upper port is further exported.If light path need to be switched to second channel, only the rotation angle of MEMS need be adjusted, reflected light will change the lens of below from microlens array into and export coupling, from the optical fiber cable of the lower port of device, export the most at last.
Embodiment 2: as shown in Figure 2:, input-output system 101 changes three optical fiber heads into, output light now is transmitted on rotary MEMS103 after condenser lens 102 is focused on, when need to export from upper port, MEMS will rotate and adjust catoptrical angle, make its incident lens direction on the lower side, the optical fiber cable that finally through the refraction of lens, will be coupled to upper port is further exported.If light path need to be switched to second channel, only the rotation angle of MEMS need be adjusted, reflected light will change into from the top of lens and export coupling, from the optical fiber cable of the lower port of device, export the most at last.
Embodiment 3: as shown in Figure 3, in order to optimize the relatively long problem of light path that corner-type MEMS 1 X 2 photoswitches exist before this, by introducing knuckle reflecting prism 104, further optimize space length, carry out the volume of reduction of device by folded optical path.
Embodiment 4: as shown in Figure 4: the first input-output system 201 is two optical fiber, the output light of two optical fiber is through the lenticule combined focus of the first microlens array 202 tops to parallel-moving type MEMS catoptron, and now the lenticule of the light of reflection below combine by microlens array optical fiber from two optical fiber in left side is further exported.If parallel-moving type MEMS is removed, light, by the output that is coupled of the lenticule of the below of the second microlens array 202 by right side, certainly, also can make its deviation be exported to the top lenticule by technological means.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
