Abstract
Accurate control of the photoluminescence (PL) emission wavelength over the range of 1.00–1.55μm has been achieved using GaIn(N)As multiple quantum well (MQW) structures, grown by plasma-assisted molecular beam epitaxy. By limiting the In content to 30%, hence limiting the overall strain, wavelength-specific MQWs can be grown through simple control over the N content (0%–5%). High crystalline quality and compositional control are demonstrated using high-resolution x-ray diffraction, secondary-ion mass spectroscopy, PL, and subsequent comparison to theoretical calculations using a ten-band k∙p band-anticrossing model. The results reveal adherence to Vegard’s law over a larger compositional range for GaInNAs than GaNAs.
