Am. Jones et al., ALUMINUM-FREE STRAINED-LAYER LASERS EMITTING AT 1.14 MU-M ON LOW-COMPOSITION INGAAS-N SUBSTRATES BY METALORGANIC CHEMICAL-VAPOR-DEPOSITION, IEEE photonics technology letters, 9(10), 1997, pp. 1319-1321
Broad-area (W = 150 mu m) single-quantum-well (SQW) lasers have been s
uccessfully fabricated on n-type In0.03Ga0.97As substrates without inc
orporating aluminum-containing alloys. The strained-layer InGaP-GaAs-I
nGaAs heterostructure was grown by atmospheric pressure metalorganic c
hemical vapor deposition. Due to both the increased substrate lattice
constant and the partial strain compensation supplied by the tensile-s
trained GaAs optical guiding layers, a peak emission wavelength of 1.1
403 mu m is obtained for a 1-mm cavity length.
