Abstract

We present an implementation of the Pound-Drever-Hall locking technique on a monolithically integrated single frequency tuneable ring laser fabricated using InP active-passive integration technology. The laser which is based on three cascaded asymmetric Mach-Zehnder interferometers is locked to a fibre Fabry-Perot interferometer with 1 MHz full-width at half-maximum. The electric feedback signal is fed to a separate intracavity electro-refractive modulator which controls the wavelength of the lasing mode. We demonstrate the laser wavelength stabilization on long time scales. We intend to use such an integrated stabilised laser in a fibre based sensing system.
