Abstract
We present a theoretical investigation of a novel staircase-like light emitter based on the GaAs/GaxAl1−xAs material system. The emission wavelength is around 12 μm. The device operation is based on the intersubband bound-to-bound transition. The energy band profile of the structure has been solved self-consistently. We have also calculated the oscillator strength.
