EXPERIMENTAL-STUDY OF LCI LASERS FABRICATED BY SINGLE MOCVD OVERGROWTH FOLLOWED BY SELECTIVE DOPANT DIFFUSION

We report the design, fabrication, and characterization of lateral cur rent injection (LCI) lasers made using a single etch-and-regrowth foll owed by selective dopant diffusion. Devices are characterized electric ally and optically from 10 to 300 K, Using the recently developed theo ry of the LCI laser, the threshold current, spontaneous efficiency, an d stimulated efficiency are related to physical mechanisms that underl ie the operation of this promising family of devices, We explore the p rospects for LCI lasers to enable monolithic photonic integrated circu its and functional optoelectronic devices.
