Summary form only given. Semiconductor lasers with optical efficiencies >1 have been created by monolithically connecting several active regions in series within a single optical waveguide. This is accomplished by epitaxially stacking a multiple of pin-MQW active regions with intermediate n/sup ++/-p/sup ++/ back-diodes which enable the entire terminal current to flow through each active region in series.
