Diode lasers based on InAsSb/InAsSbP with separate electrical and opti
cal confinement, emitting in the wavelength interval 3-4 mu m, are inv
estigated. The lasers attain a higher operating temperature when elect
rical confinement is created by means of type-II heterojunctions. Inte
rface Auger recombination is suppressed in lasers of this type, and th
e experimental current density is close to the theoretically calculate
d value for the case of predominant volume Auger recombination at a te
mperature of 180-220 K. (C) 1997 American Institute of Physics.
