Abstract

We developed a compact gate switch with monolithic integration of all-optical cross-phase modulation (XPM) in a Mach-Zehnder interferometer, by area-selective implantation for intersubband transition in InGaAs/AlAsSb CDQWs. By injecting pump light through a TE/TM beam combiner, XPM was induced in one MZI arm, and gating operation was realized.
