Observation of Photon-driven Electronic Transport in Quantum Cascade Lasers

Abstract

We report a series of femtosecond pump-probe measurements on quantum cascade lasers operating below and above threshold; the gain recovery dynamics reveal how quantum stimulated emission drives the current through the cascade heterostructure, which we refer to as photon-driven transport.
