Optical alignment in laser modules represents major cost barriers for subscriber systems. From the point of high volume production and low cost views, integration of the laser and the spot-size transformer is desirable. Recently we have demonstrated a narrow beam divergence tapered thickness MQW spot-size transformer integrated Fabry-Perot BH InGaAsP MQW lasers using a selective area growth technique. Our tapered thickness waveguide MQW spot-size transformer is fully compatible for the laser fabrication process so that an increase in the fabrication cost will be minimized. Here we introduce our structure and lasing performance.
