Ultrafast optical signal processing with Symmetric-Mach-Zehnder-type all-optical switches

摘要

We demonstrate various types of ultrafast all-optical signal processing with Symmetric-Mach-Zehnder (SMZ) all-optical switches incorporating semiconductor optical amplifiers. By using a hybrid-integrated SMZ switch, error-free operations of 336-Gb/s demultiplexing, 42-Gb/s pulse regeneration, and 42-Gb/s wavelength conversion have been achieved. We have also verified the capability of higher bit rate operation by showing 84-Gb/s pulse regeneration and 168-Gb/s wavelength conversion with the variants of the SMZ switch.
