Abstract

The intersubband transitions in the communications wavelength range with peak absorption wavelength were presented. Multiple quantum well (MQW) samples were grown by molecular beam epitaxy on sapphire substrate with buffer layers of varying composition and thickness. The samples contained 15 nominally identical repetitions and a GaN buffer layer. Conventional pump-probe technique was used to measure the intersubband electron scattering time.
