Abstract
A novel laser structure containing four amplifiers and a monolithically integrated passive multimode interference (MMI) coupler has been fabricated using quantum-well intermixing. The device has a threshold current of 120 mA, a slope efficiency of 10% per facet and generates over 180 mW of optical power in a single transverse mode output waveguide
