| 摘 要： | 设计了一种光电混合光纤旋转连接器,能实现相对旋转的光信号在较大对准误差范围内低损耗连接.旋转状态下的自聚焦透镜准直光纤输出的光信号,并由PIN光电探测器将其转换为电信号,冉由激光器根据电信号再生出原始光信号继续在光纤通讯系统中传输.该光电混合光纤旋转连接器在离轴偏移量至520μm或对准倾斜角至0.5°时的附加耦合损耗为0.3 dB,而采用双自聚焦透镜的光纤旋转连接器要获得小于3 dB的插入损耗,其离轴偏移或倾斜角度必须小于100 μm和0.10°相比之下,本文设计的光纤旋转连接器能降低系统对机械加上及装配精度的要求,具有较高的实用价值.

| Abstract: | An opto-electronic hybrid fiber optical rotary joint(FORJ)is designed,which can keep connecting between two relatively rotary optical signal in a larger misalignment range with low interconnection loss.The rotary graded-index(GRIN)lens collimates the light from the SM fiber,PIN photo detector transfers the optical signal to electric signal,and the semiconductor laser gives out the regenerate optical signal and lets the ray keep up transmitting in fiber communications system.The coupling loss is just 0.3 dB ... |
