Circular, narrow beam emission of 1.3-µm surface-emitting laser with monolithically-integrated InP lens for direct fiber coupling


Circular, narrow beam emission of a lens-integrated surface-emitting laser operated at 1.3-µm wavelength was demonstrated. The laser consists of a distributed feedback laser cavity monolithically integrated with an etched 45° total reflection mirror and an etched InP lens. The profile of the etched InP lens was estimated to be a highly… (More)
