Heterostructure semiconductor lasers prepared by molecular beam epitaxy
--0.72-0.88 ..mu..m (AlGa)As, 1.3-1.65 ..mu..m GalnAsP and AlGaInAs, and 1.78 ..mu..m AlGaSb double-heterostructure (DH) lasers were prepared by molecular beam epitaxy. For AlGaAs DH lasers very low 300 K threshold current densities and long operating life (mean time to failure >10 h at 300 K) were achieved and optical transmitters containing MBE-grown lasers have been field-tested. For lasers with lasing wavelength >1 ..mu..m, MBE is in the development stage. The unique capabilities of MBE as an epitaxial growth technique and its important contributions to the field of optoelectronics are illustrated by a discussion of a new class of laser structures including quantum well heterostructure of GaAs/ Al Ga /SUB 1-x/ As and Ga /SUB 0.47/ In /SUB 0.53/ As/InP, double-barrier double-heterostructure lasers. These new lasers, made possible by MBE, have characteristics unmatched by conventional liquid phase epitaxial growth techniques.
