A MOCVD technology for growth of InGaAs/GaAs/InGaP laser heterostructures o
n a modified Epiquip VP-50-RP installation was developed. Mesa stripe laser
diodes with threshold current density J(th) = 100-200 A/cm(2), internal op
tical loss alpha (i) = 1.3-1.7 cm(-1), and internal quantum efficiency eta
(i) = 60-70% have been fabricated. A CW output optical power of 5 W has bee
n obtained for a single 100-mum-wide aperture mesa stripe laser diode emitt
ing at 1.03 mum. It is shown that use of AlGaAs waveguide layers, which inc
rease the conduction band barrier offset, lowers the temperature sensitivit
y of laser heterostructures within the temperature range 10-80 degreesC. (C
