Selectively doped double-heterojunction lateral current injection ridge waveguide AlGaAs/GaAs laser

Abstract
A new type of laser structure which utilizes the selectively doped double-heterojunction (SDH) structure for lateral current injection (LCI) was proposed. A ridge waveguide AlGaAs/GaAs laser based on the SDH-LCI scheme was demonstrated to lase at the very low threshold current of 11.5 mA. The compatibility of this new laser structure with electronic devices is discussed.
