The operation in the 1020 nm wavelength range of strained-layer InGaAs/GaAs
separate-confinement-heterostructure lasers grown by molecular beam epitax
y is reported. The active region is formed by a single 80 Angstrom thick In
GaAs quantum well with an indium content of 25%, which is close to critical
parameters. This paper provides the operating characteristics of broad-are
a uncoated Fabry-Perot structures with cavities of 700 mum length measured
in the pulsed regime. (C) 2001 John Wiley & Sons, Inc.
