Highly integrated optical modules for >400-G coherent optical links

Abstract

Small coherent optical transceivers are demanded in metro-area networks and data-center interconnects. Accordingly, required mechanical dimensions of optical components are shrinking. We present two types of highly-integrated optical modules for >400-Gb/s coherent optical links. Our developed wavelength-tunable laser module consists of an ultra-compact DBR/Ring laser chip and PLC-based wavelength locker. The laser module covers the full C-band with narrow linewidth of <100 kHz and fiber output power above 17 dBm. Furthermore, we demonstrate a tiny transmitter-receiver optical sub-assembly that integrates all required optical components according to the Optical Internetworking Forum specifications. The achieved electro-optical and optical-electro bandwidths are >40 GHz.
