The RF-modulation emission characteristics of a MQW DFB laser monolithically integrated with a laterally tapered spot-size transformer on InGaAsP/InP were investigated and key results were presented. Despite the relatively simple design of the devices they are characterized by good high speed lasing properties with a direct modulation response exceeding 5 GHz. A simple low loss chip-fiber coupling arrangement with large optical alignment tolerances was demonstrated and is regarded as a particular advantage of these devices. Their experiments confirm the attractivity of this integration concept for low cost laser components in optical transmission systems.
