Monolithically integrated tunable laser source operating at 2µm for gas sensing applications

Abstract

A tunable laser operating from 2015 - 2040 nm realized as a monolithic InP photonic integrated circuit is presented. The laser uses an intracavity tuning mechanism based on parallel asymmetric Mach-Zehnder interferometers with electro-refractive modulators. The device is intended for a single line gas spectroscopy and was designed and fabricated using a generic integration technology platform.
