摘要

基于Si-Ge-silica单片光子集成技术，我们开发了一种22gbit /s × 16ch WDM接收机，其中16ch通道分离的SiOx AWG和Ge光电二极管被单片集成。AWG-PD器件的光纤- pd响应率为0.29 A/W，通道间串扰小于20 dB, 16个通道均能成功接收22gbit /s的信号。此外，我们演示了40公里传输12.5 Gbit/s的信号，并在没有透阻放大器的情况下，在BER为10-9时获得了-6.8 dBm的灵敏度。

22-Gbit/s × 16-ch WDM receiver based on a Si-Ge-silica monolithic photonic platform and its application to 40-km transmission

We developed a 22-Gbit/s × 16-ch WDM receiver based on a Si-Ge-silica monolithic photonic integration technology, in which a 16-ch SiOx AWG with 1.6-nm channel separation and Ge photodiodes are monolithically integrated. The AWG-PD device exhibited fiber-to-PD resoponsivity of 0.29 A/W and inter-channel crosstalk of less than 20 dB, and successfully received 22 Gbit/s signal for all 16 channels. In addition, we demonstrated 40-km transmission of 12.5 Gbit/s signal and obtained sensitivity of -6.8 dBm at BER of 10-9 without transimpedance amplifiers.
