Abstract

Complete integration of optical laser sources and waveguides with electronics on a single semiconductor wafer has been a long sought after and elusive goal. Future development of optoelectronic integrated circuits (OEICs) hinges on the development of monolithically integrated laser/waveguide systems with low threshold currents and high injection efficiency into the passive waveguide. This paper reports progress in developing just such a high efficiency Transverse Junction Stripe¹ (TJS) laser source integrated with an external passive waveguide suitable for optical interconnection applications. Threshold current as low as 60 mA and injection efficiencies as high as 40% are reported.
