Room-temperature heterojunction laser diodes from vapor-grown In/sub 1-x/Ga/sub x/P/GaAs structures

  • 1. RCA Labs., Princeton, NJ

Description

Vapor-grown epitaxial structures of In0.5Ga0.5P/GaAs have yielded heterojunction laser diodes with room-temperature threshold current densities as low as 8000 A/cm2 for a 2.5-μm GaAs laser cavity width. Differential external quantum efficiencies as high as 30% have been attained. Measurements suggest the existence of internally ``trapped'' laser modes due to the large refractive-index discontinuity at the In0.5Ga0.5P–GaAs interfaces.
