Abstract

Heterojunction laser diodes with GaxIn1−xP active layer have been fabricated from GaAs−Ga0.51In0.49P−Ga0.32 Al0.68As−GaAs heterostructures made by liquid phase epitaxy from Ga−rich and In−rich solutions. Stripe−geometry lasers have been operated at 77 K with threshold current densities as low as 2500 A/cm2 with an emission wavelength of λ=638 nm.
