Abstract

Broad-area InAs quantum dot lasers and segmented contact devices have been fabricated using monolithically grown InAs/InAlGaAs/InP active structures on nano-patterned (001) silicon substrates. The device optoelectronic properties, optical gain and absorption have been studied and compared to structures with a nominally identical active region, grown on a native indium phosphide substrate.
