Abstract

We have demonstrated balanced coherent detection using distributed balanced traveling-wave photodetectors integrated with single mode polymer optical waveguides. Balanced distributed traveling-wave photodetectors having 3 dB bandwidth of 20 GHz exhibited 20 dB signal to noise ratio improvement measured at 15 GHz modulation frequency in a balanced coherent detection demonstration.

摘要

我们已经展示了使用与单模聚合物光波导集成的分布式平衡行波光电探测器进行平衡相干检测。在平衡相干检测演示中，具有20 GHz 3 dB带宽的平衡分布式行波光电探测器在15 GHz调制频率下测量时，信噪比提高了20 dB。
