中文摘要: |
提出了一种实现高速并行光接收模块中光电探测器(PD)列阵与光纤列阵精密无源耦合对准的方法,设计并制作了用于这种光学精密对准的所有组件,并用此耦合对准方法完成了PD阵列与光纤阵列之间的光耦合,制作出了12信道并行光接收模块。耦合完成的PD列阵与光纤列阵的对准误差小于1μm,从光纤列阵耦合进入PD列阵的光功率耦合效率大于80%。此模块采用工作波长为850nm的高速PIN型PD列阵作为光接收器件,输入光信号直接由12信道的光纤阵列耦合进入PD列阵中。此并行光接收模块的单信道传输速率大于等于3.318Gbit/s |
英文摘要: |
An advanced structure of passive optical coupling for the application of optical interconnect with the high coupling efficiency and the high alignment precision was proposed, and a 12 channel high speed parallel optical receiver module based on this advanced coupling technique was designed and fabricated using an 850nm GaAs photoelectric detector (PD) array and a fiber array. The error amount of coupling was less than 1μm and the coupling efficiency was more than 80 percent. The optical signals was directly coupled into PD array through a fiber array. We got a wide open eye diagram with data rate of 3.318Gbit/s for each channel and the total data rate of 40Gbit/s from the receiver module. Compared with active optical coupling, the passive optical coupling simplified the coupling process and enhanced the work efficiency. It’s suited for large scale production |
