Abstract

We demonstrate a single-ended colorless coherent receiver using symmetric 3x3 couplers for optical hybrids. We show that the receiver can achieve colorless reception of fifty-five 112-Gb/s polarization-division-multiplexed quadrature-phase-shift-keyed (PDM-QPSK) channels with less than 1-dB penalty in the back-to-back operation. The receiver also works well in a long-haul wavelength-division-multiplexed (WDM) transmission system over 2560-km TrueWave® REACH fiber.

摘要

我们展示了一种使用对称3x3耦合器实现光混合的单端无色相干接收机。我们表明，该接收机在背对背操作中能够实现对55个112 Gb/s偏振复用正交相移键控（PDM-QPSK）信道的无色接收，代价小于1 dB。该接收机在2560公里长的TrueWave® REACH光纤的长途波分复用（WDM）传输系统中也能良好工作。
