100-Gbit/s optical receiver front-end module technology

Abstract

We have been developing a 100-Gbit/s-class optical receiver front-end module with a hybrid integration structure using silica-based planar lightwave circuit technology to perform demultiplexing and demodulation in digital coherent photonic network systems. In this article, we describe the module structure and the integration technology that we have developed at NTT Photonics Laboratories.
