Abstract

It is shown that direct-gap covalent semiconductors, such as GaAs, should exhibit electric-field-induced Franz-Keldysh-like structures in their two-photon absorption spectra. These structures are evaluated employing exciton theory; the resulting line shapes are shown to be proportional to the line shapes for one-photon "forbidden" transitions, a property that greatly facilitates computations of the two-photon absorption.
