Abstract

We theoretically analyze the effect of current-induced polarization dependence of absorption (fundamental and intersubband) and gain in degenerate semiconductors. The sign of the current-induced polarization selectivity of absorption is shown to depend on the energy of the initial (or final) state of the transition with respect to the Fermi level and, therefore, on the photon energy. The effect is predicted to be important for understanding and, potentially, engineering polarization properties of devices such as vertical-cavity surface-emitting lasers. © 2001 American Institute of Physics.
