Abstract

We demonstrate a monolithically integrated dual-quadrature coherent receiver with greater than 30 nm widely-tunable SG-DBR local oscillator, signal input SOAs, a 90° optical hybrid and four 10 GHz photodetectors. With 20 Gb/s NRZ-QPSK, we demonstrate a required OSNR of 10 dB for a BER of 10(-3) at four different wavelengths.

摘要

我们展示了一种单片集成的双正交相干接收机，它具有大于30纳米的宽调谐SG-DBR本地振荡器、信号输入半导体光放大器、一个90°光混合器和四个10吉赫兹光电探测器。对于20吉比特/秒的NRZ-QPSK信号，我们在四个不同波长下实现了误码率为10（-3）时所需的光信噪比为10分贝。
