Tunable 4-channel ultra-dense WDM demultiplexer with III-V photodiodes integrated in silicon-on-insulator

摘要

A tunable 4-channel ultra-dense WDM demultiplexer with 0.25nm channel spacing is demonstrated with III-V photodiodes integrated on Silicon-on-Insulator using rib waveguides. A possible application is an in-band label extractor for all-optical packet switching.
