Abstract

A dual-quadrature coherent receiver based on a polymer planar lightwave circuit (PLC) is presented. This receiver comprises two separate optical 90°-hybrid chips made of polymer waveguides and hybridly integrated with InGaAs/InP photodiode (PD) arrays. The packaged receiver was successfully operated in 112 Gbit/s dual-polarization quadrature phase-shift keying (QPSK) transmission experiments. In back-to-back configuration the OSNR requirement for a BER value of 10(-3) was 15.1 dB which has to be compared to a theoretical limit of 13.8 dB.

摘要

本文介绍了一种基于聚合物平面光波电路（PLC）的双正交相干接收机。该接收机由两个独立的光学90°混合芯片组成，这些芯片由聚合物波导制成，并与InGaAs/InP光电二极管（PD）阵列混合集成。封装后的接收机在112 Gbit/s双偏振正交相移键控（QPSK）传输实验中成功运行。在背对背配置中，误码率（BER）值为10^(-3)时的光信噪比（OSNR）要求为15.1 dB，而理论极限为13.8 dB，两者可作比较。
