## Abstract We have theoretically demonstrated population inversion between two conduction subbands in a silicon quantum well in a triple‐well structure with Si and SiGe, considering tunneling, radiative‐ and non‐radiative‐acoustic, and __g__‐phonon transitions. The gain spectra are then calculated
