Abstract
Microscopic semiconductor theory is applied to an indirect Si-type semiconductor quantum well system. We discuss the absorption and stimulated emission of light accompanied by the creation or annihilation of phonons. We find strong differences to the optical properties of conventional direct semiconductors, including an asymmetric behavior where the maximum gain strongly exceeds the low-density absorption.
