Abstract
Dilute nitride type-II "W" structures have potential for lasing at 1.55 microns (on GaAs substrates) and in the mid-infrared (3-6 microns, on InP substrates). The former active regions utilize (In)GaAsN/GaAsSb/(In)GaAsN/GaAs quantum wells, whereas the latter are based on InAsN/GaAsSb/InAsN/GaInP structures. Following a review of the theoretical rationale, we will present some preliminary MOCVD growth results for the GaAs-based type-II structures, along with their characterization by x-ray, TEM, and photoluminescence. The experimental energy gaps corresponding to the layer compositions determined from characterization are in good agreement with calculations based on the 10-band k×p formalism.
