Abstract

In this work, we present results from the stabilization of an integrated single frequency InP diode laser with an extended cavity using the Pound-Drever-Hall locking technique. The laser is a multi-section DBR laser with an intra-cavity ring resonator. It is locked to a 1 MHz wide resonance of a highly stable Fabry-Perot etalon via electrical feedback which is applied on the rear DBR section. The DBR section is used in reverse bias to tune the lasing mode thus avoiding any thermal effects. We show measurements that confirm the drift stabilization of the laser to an etalon resonance for over 10 minutes and linewidth measurements using the delayed self-heterodyne method. The latter show a reduction of the laser linewidth below 50 kHz which is at the moment limited by the time delay of the current feedback loop.
