Abstract

We develop a microscopic model for the recently demonstrated double quantum dot (DQD) maser. In characterizing the gain of this device we find that, in addition to the direct stimulated emission of photons, there is a large contribution from transitions that involve the simultaneous emission of a photon and a phonon. This phonon assisted process controls the masing transition because it dominates the gain in the region of large population inversion. These theoretical results are compared to experiment and good agreement is found.
