Abstract
The measurement of photoluminescence (PL) and electroabsorption spectra in strain compensated GaNAs/GaAsSb type-II quantum wells grown on GaAs substrates using molecular beam epitaxy is reported. The bilayer quantum well (GaN0.02As0.98/GaAs0.8Sb0.2) shows a room temperature PL peak at 1300 nm, and a blue shift of the Franz-Keldysh type oscillation is observed in the multiple quantum wells consisting of GaN0.03As0.97 and GaAs0.84Sb0.16
