Magneto-Stark polaron states in semiconductor quantum wells
arXiv:1005.3693
Abstract
We study theoretically the effect of a lateral electric field on the magneto-polaron states in a quantum cascade laser under a quantizing magnetic field. We show that this problem fits the original Fano model of a discrete state coupled to a continuum, present a detailed analysis of magneto-Stark polaron resonances, and finally discuss the strong consequences on the optical characteristics of an operating structure.
