Photonic bus with loop signal routing and multichannel wavelength selection on a single silicon-on-insulator platform

摘要

We have demonstrated a silicon-on-insulator-based photonic bus with integrated splitters, a demultiplexer, attenuators, and a multiplexer for loop signal routing and multichannel optical wavelength selection. The integrated photonic bus has demonstrated a 33+ dB optical cross talk, a 32+ dB extinction ratio, and a rise time of 7.6 (mu)s with two-stage Mach-Zehnder attenuators.
