Abstract

Terahertz gain without population inversion is studied in thin III-V semiconductor quantum wells. Nonequilibrium hole populations leading to intervalence gain in the transverse electric mode are investigated. The results are obtained with a Keldysh Nonequilibrium Green's Functions approach that takes into account bandstructure, manybody and nonequilibrium effects.
