下面结合附图和实施例对本公开进行详细的说明。
参考图1-图3，其中，图1是本公开第一方面实施例的光连接装置10的结构示意图，图2是图1中的光连接装置10的***示意图，图3是图2中的光连接装置10中的光耦合件13的一实施例的剖视图。根据本公开的一实施例，光连接装置10包括第一连接器11、第二连接器12以及光耦合件13。
其中，根据本公开实施例的光连接装置10具体是针对电路板面出光的直角耦合需求而提出的一种嵌入式或表面贴装式的能够使光线进行偏转的连接装置，包含一体化准直反射部件和光学连接部件。
需说明的是，在本实施例中，上述“一体化准直反射部件”具体为光耦合件13，包含透镜阵列、反射斜面、导向结构等，以实现发散光线的准直、反射、汇聚。而上述“光学连接部件”为一种具有光连接和光传输功能的部件，具体可以是带有光传输介质的连接头或带有发光/收光器件的结构件，也即第一连接器11和第二连接器12。
其中，光线在传输过程中通常是发散的，即开始相邻的两条光线经传播后会相离越来越远。而准直通俗来说就是保持光线之间是平行的。
具体地，第一连接器11连接至外部的第一导光介质21，例如，多个并排设置的光纤，且该多个光纤靠近光耦合件13的一端嵌设于第一连接器11中，以由第一连接器11对该多个光纤进行固定和集束。在其它实施例中，第一导光介质21还可以为封装有多个芯层的光波导，且该光波导嵌设于第一连接器11对应形成的凹槽中，以与第一连接器11实现连接。
同理，第二连接器12连接至外部的第二导光介质22，例如，多个并排设置的光纤，或封装有多个芯层的光波导，以通过第二连接器12对第二导光介质22进行固定和集束。
进一步地，光耦合件13包括第一侧面1301、第二侧面1302以及第三侧面1303，且第一侧面1301与第二侧面1302相垂直，第三侧面1303与第一侧面1301和第二侧面1302之间的夹角均呈45°。
又进一步地，光耦合件13的第一侧面1301上还形成有第一平凸透镜131，第一连接器11与光耦合件13的第一侧面1301相连接，以使第一导光介质21的延伸方向与第一侧面1301垂直且第一平凸透镜131位于第一导光介质21的延伸方向上，此时第一导光介质21与第一平凸透镜131间隔设置。
光耦合件13的第二侧面1302上形成有第二平凸透镜132，第二连接器12与光耦合件13的第二侧面1302相连接，以使第二导光介质22的延伸方向与第二侧面1302垂直且第二平凸透镜132位于第二导光介质22的延伸方向上，此时第二导光介质22与第二平凸透镜132间 隔设置。
其中，在第一导光介质21中传输的光线向光耦合件13发出光线时，该光线能够由第一平凸透镜131的外侧入射至光耦合件13的内部，以由第一平凸透镜131进行准直和汇聚后，在光耦合件13的第三侧面1303上进行反射，进而由第二平凸透镜132的外侧出射，以分别对应进入到第二导光介质22进行传输。
根据本公开实施例的光连接装置，其第一连接器连接至外部的第一导光介质，第二连接器连接至外部的第二导光介质，且其光耦合件的第一侧面垂直于第二侧面，第三侧面与第一侧面和第二侧面之间的夹角均呈45°，第一侧面上形成有第一平凸透镜，第二侧面形成有第二平凸透镜，第一连接器与光耦合件的第一侧面连接，以使第一导光介质的延伸方向与第一侧面垂直且第一平凸透镜在第一导光介质的延伸方向上，第二连接器与光耦合件的第二侧面连接，以使第二导光介质的延伸方向与第二侧面垂直且第二平凸透镜在第二导光介质的延伸方向上，以在第一导光介质对应传输的光线由第一平凸透镜外侧入射至光耦合件内部时，光线能够在第三侧面上进行反射，且由第二平凸透镜外侧出射而进入到第二导光介质进行传输，且光连接装置中的连接器和波导能够灵活地进行拆解，以分别对连接器和波导行返修、维护以及升级处理。
可理解的是，第一导光介质21包括的光路的数量可以是多个，第一平凸透镜131、第二平凸透镜132以及第二导光介质22包括的光路的数量均为多个，且这四者的数量均相同，并一一对应，以能够有效地对由第一导光介质21发出、并入射至光耦合件13中的光线进行准直、反射、汇聚，之后光线分别对应进入到第二导光介质22中，并由第二导光介质22继续进行传输。在本文中，光路的数量可以指光纤的数量，或光波导的芯层的数量。每一组相互对应的第一导光介质21、第一平凸透镜131、第二平凸透镜132以及第二导光介质22均对应一光通道，进而能够实现一光互联线路逻辑，此时光路连接完成，相应光线能够基于每一光通道对应实现低损耗的90°反射及传输。
在另一实施例中，第一平凸透镜131和第二平凸透镜132的数量可以相同，且大于第一导光介质21包括的光路的数量，而第二导光介质22包括的光路的数量等于第一导光介质21包括的光路的数量，以在后续需要更换包括更多数量光路的第一导光介质21和第二导光介质22时，仍能采用光耦合件13及其第一平凸透镜131和第二平凸透镜132进行光互联，从而有效地扩宽了第一平凸透镜131和第二平凸透镜132的适用范围。
上述方式，因第一导光介质21通过第一连接器11与光耦合件13实现连接，第二导光介质22通过第二连接器12与光耦合件13实现连接，能够在后续灵活地对连接器和光耦合件13进行拆解，进而更便捷地分别对连接器和波导行返修、维护以及升级处理。另外，通过光耦合件13的第一侧面1301、第二侧面1302以及第三侧面1303与第一导光介质21和第二导光介质22的对应设置，实现相应光线的90°反射及传输，相较于在弯曲光路(如弯曲光纤或弯曲光介质)中在自由空间中的传输，光的损耗也更小。此外，光连接装置10具体还可以内嵌 于相应的电路板中，以提高电路板的集成度，且第一连接器11和第二连接器12的结构也相较更简单，易于成型制造，也有效降低了光连接装置10的制造成本。
在一实施例中，光耦合件13由对所传输的光线有良好的透过性、且具有特定折射率的材料一体成型制造而成。
可选地，光耦合件13的折射率大于√2，以在由第一平凸透镜131外侧入射至光耦合件13的内部的光线投射到光耦合件13的第三侧面1303时，能够发生全反射，进而能够由第二平凸透镜132的外侧出射，以进入到第二导光介质22进行传输，从而能够有效降低光的损耗。
需说明的是，该全反射的全称为全内反射，也即当光线从高折射率介质进入低折射率介质时，入射角大于某一临界角时折射光线将消失，所有入射光线将发生反射而不进入低折射率介质。
可理解的是，如图4所示，图4是光线反射原理图，其中，以第一导光介质21为发光元件，第二导光介质22为收光元件，且对应实现光线的准直、反射、汇聚功能的光耦合件13的折射率为n1(n1为任一合理的正数)，光耦合件13的第三侧面1303背离第一导光介质21的另一侧介质的折射率为n2为例，可知在光耦合件13的折射率满足n1>n2/sinθ1时，由于全反射原理，该第三侧面1303可以使从一端透镜即第一平凸透镜131进入的光线反射至另一端透镜即第二平凸透镜132中出射。
其中，θ1为光线的入射角，反射斜面与光线的夹角即入射角θ1一般为45°，也可根据具体的使用场景进行调整。而且，n2通常为空气的折射率，数值可取1。
由此可知，在光耦合件13的折射率满足n1>1/sin45°，也即n1>√2时，进入到光耦合件13内的光线能够在其第三侧面1303发生全发射。
可选地，光耦合件13具体是采用光学玻璃或光学塑料制成。
可选地，该光学塑料具体为PMMA(聚甲基丙烯酸甲酯)、TPX(聚甲基戊烯)、PS(聚苯乙烯)、PC(聚碳酸酯)或PEI(聚醚酰亚胺)等任一合理的光学塑料，本公开对此不做限定。
在一实施例中，光耦合件13的第三侧面1303背离其第一侧面1301的一侧上还设置有反射膜(图未示出)，以在第一光波导对应传输的光线由第一平凸透镜131外侧入射至光耦合件13内部时，该光线能够在第三侧面1303上进行反射，且由第二平凸透镜132外侧出射而进入到第二光波导进行传输，且此时光耦合件13的折射率可不考虑能够对应实现全反射的设定条件，因为此时发生镜面反射。
在一实施例中，光耦合件13的第一侧面1301形成有第一凹槽133，且第一平凸透镜131形成在第一凹槽133的底部，以与第一导光介质21间隔设置。
可理解的是，为保证第一连接器11的一侧在贴设于第一侧面1301时，第一平凸透镜131能够与第一导光介质21及第一连接器11间隔设置，在第一侧面1301上形成第一凹槽133，以使第一平凸透镜131不超出第一侧面1301所在的平面。
同理，光耦合件13的第二侧面1302还形成有第二凹槽134，而第二平凸透镜132形成在第二凹槽134的底部，以与第二导光介质22间隔设置。
在一实施例中，第一平凸透镜131的数量具体为多个，且多个第一平凸透镜131相互间隔并呈阵列排布于第一凹槽133的底部。
同理，第二平凸透镜132的数量具体为多个，且多个第二平凸透镜132相互间隔并呈阵列排布于第二凹槽134的底部。
可选地，第一平凸透镜131的数量为4的正整数倍。
可理解的是，透镜阵列，也即第一平凸透镜131阵列及第二平凸透镜132阵列具体是由通光孔径及浮雕深度为微米级的透镜组成的阵列，它不仅具有传统透镜的聚焦、成像等基本功能，而且具有单元尺寸小、集成度高的特点，使得它能够完成传统光学元件无法完成的功能，并还能构成许多新型的光学***。
其中，第一平凸透镜131和第二平凸透镜132的数量分别具体为12个，而在其它实施例中，如图5所示，图5是图2中的光耦合件13的又一实施例的剖视图，第一平凸透镜131和第二平凸透镜132的数量可以相同，且为8、16、24或48等其他任一合理的数量，本公开对此不做限定。
可理解的是，上述透镜阵列，也即第一平凸透镜131阵列及第二平凸透镜132阵列的数量和位置具体分别与第一连接器11和第二连接器12相对应，以使从第一导光介质21出射的光线能够对应汇聚成平行光，且使平行光汇聚后，射入到第二平凸透镜132阵列中。
在一实施例中，光耦合件13的第一侧面1301上还形成有凸出的第一导向柱135，且第一连接器11的一侧面上形成有与第一导向柱135对应的第一定位孔111，第一导向柱135能够嵌设于第一定位孔111内，以实现第一连接器11与光耦合件13的连接。
同理，光耦合件13的第二侧面1302上也形成有凸出的第二导向柱136，第二连接器12的一侧面上形成有与第二导向柱136对应的第二定位孔121，第二导向柱136能够嵌设于第二定位孔121内，以实现第二连接器12与光耦合件13的连接。
可选地，第一导向柱135和第二导向柱136呈圆柱体或方体等任一合适的柱体设置，且相应的第一定位孔111和第二定位孔121也相应地针对圆柱体或方体等任一合适的柱体设置，本公开对此不做限定。
在一实施例中，光耦合件13的第一侧面1301的外侧边缘还形成有凸出的、一侧开口的第一安装板137，且第一连接器11容置于第一安装板137的该一侧开口对应的第一容置腔中，以与光耦合件13连接。
同理，光耦合件13的第二侧面1302的外侧边缘也形成有凸出的、一侧开口的第二安装板138，且第二连接器12容置于第二安装板138的与该一侧开口对应的第二容置腔中，以与光耦合件13连接。
在一实施例中，如图6所示，图6是图1中的光连接装置10中的第一连接器11的一实施 例的结构示意图，第一连接器11连接的第一导光介质21具体为并排设置的光纤，且该光纤嵌设在第一连接器11形成的通孔113中，并借助固化胶112(一般为环氧树脂)在第一连接器11的背离光耦合件13的一侧面对光纤进行固定。而且，该光纤嵌入第一连接器11的通孔113中的一端不超出第一连接器11面向光耦合件13的一侧面，并能够沿通孔113的通道延伸方向发出光线，进而使光线由第一平凸透镜131外侧入射至光耦合件13内部。
同理，第二连接器12连接的第二导光介质22也可以是并排设置的光纤，且第二连接器12的相应结构和连接设置同于第一连接器11。具体地，第二连接器12连接的第二导光介质22具体为并排设置的光纤，且该光纤嵌设在第二连接器12形成的通孔(图未示出)中，并借助固化胶(一般为环氧树脂)在第二连接器12的背离光耦合件13的一侧面对光纤进行固定。而且，该光纤嵌入第二连接器12的通孔中的一端不超出第二连接器12面向光耦合件13的一侧面，并能够沿该通孔的通道延伸方向发出光线，进而使光线由第二平凸透镜132出射而进入到第二导光介质22进行传输。
在另一实施例中，如图7所示，图7是图1中的光连接装置10中的第一连接器11的又一实施例的结构示意图，第一连接器11连接的第一导光介质21具体为平面导光介质，也即平面光波导，且该平面光波导嵌设在第一连接器11对应形成的凹槽(图未标出)中，以与第一连接器11连接。
同理，第二连接器12连接的第二导光介质22也可以是平面光波导，且第二连接器12的相应结构和连接设置同于第一连接器。具体地，该平面光波导嵌设在第二连接器12对应形成的凹槽(图未标出)中，以与第二连接器12连接。
可理解的是，上述“第一连接器11-光耦合件13-第二连接器12”的光互联架构，还可以对应变形为“激光器组件-光耦合件13-光纤连接器”、“光纤连接器-光耦合件13-光探测器组件”等，本公开对此不做限定。
