Reduced thermal cross-talk in angled etched facet individually addressable laser arrays

We have fabricated closely spaced (8 /spl mu/m) arrays of non parallel etched facet lasers. We compared the thermal cross-talk of angled lasers with that of parallel stripe lasers with same separation. The angled lasers show less than half the thermal coupling of parallel lasers. Lasers are demonstrated in two different material systems. In InGaAs these lasers produced up to 120 mW/facet with an efficiency of .24 W/A per facet.
