Abstract

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. Our experiments confirm the attractivity of this integration concept for low cost laser components in optical transmission systems
