Abstract

We have successfully demonstrated a novel InGaAsP mode-expanded MQW laser based on the adiabatic transformation of the laser rib mode into a fiber-matched ARROW waveguide. The fabrication is drastically simplified to one planar growth step and one conventional non-critical etch step. Efficient mode transformation and considerable reduction of the horizontal and vertical far-field FWHM have been achieved
