Optical gains and interband transitions of CdTe/ZnTe single quantum wells

Abstract

The optical gains of the CdTe/ZnTe single quantum wells with various CdTe widths were calculated by using a non-interacting pair Green's function and by an energy space integrated function. The interband transition energies from the ground electronic subband to the ground heavy-hole subband calculated taking into account optical gains were in qualitatively reasonable agreement with those determined from the PL spectra.
