Abstract

Extended wavelength photoluminescence emission within the technologically important 2–5 micrometer spectral range has been demonstrated from InAs1xNx and In1yGayAs1xNx type I quantum wells grown onto InP. Samples containing N 1% and 2% exhibited 4K photoluminescence emission at 2.0 and 2.7 lm, respectively. The emission wavelength was extended out to 2.9 lm (3.3 lm at 300 K) using a metamorphic buffer layer to accommodate the lattice mismatch. The quantum wells were grown by molecular beam epitaxy and found to be of a high structural perfection as evidenced in the high resolution x-ray diffraction measurements. The photoluminescence was more intense from the quantum wells grown on the metamorphic buffer layer and persisted up to room temperature. The mid-infrared emission spectra were analysed, and the observed transitions were found to be in good agreement with the calculated emission energies.
