Integrated Silicon Photonic Circuit: Monolithic 8-Channel Modulator, Tap, Vertical Coupler, and Flip-Chip Mounted Photodetector Array

摘要

This paper describes a silicon photonic circuit of eight fiber-optic input ports, each port leads through an electro-photonic modulator to a 0.95/0.05 coupler, where the 95% signal is guided to a fiber-optic output port and the 5% signal is terminated by a vertical coupler and a down-looking photodetector. Applications include telecommunication equipment requiring microsecond speed for rapid power balancing, transient suppression, and subcarrier modulation for channel tracking and system health monitoring. Circuit elements and initial measurements are described.
