Femtosecond wave mixing experiments in ZnCdSe/ZnSe quantum wells

Abstract

Extreme high order nonlinear diffracted signals are found in ZnCdSe/ZnSe quantum wells in two beam, self-diffraction geometry. Diffracted signals of all observed orders are shown to originate predominantly from excitonic resonances. Using four-wave mixing, an indication of hole-longitudinal optical phonon scattering between the heavy and the light hole states is found, and exciton-phonon interaction is studied.

Nonlinear Optical Processes Due to Polaritons and Biexcitons in a Microcavity Enclosed Quantum Well

“…In QWs of Zn 1Àx Cd x Se/ZnSe type HH and LH excitons (containing a heavy and a light hole, respectively) and also biexcitons are detected experimentally [27,28]. We shall deal with such a QW embedded in a semiconductor microcavity, the plane of which is parallel to the QW plane and perpendicular to the Oz axis.…”

Degenerate four-wave-mixing spectroscopy on epitaxially laterally overgrown GaN: Signals from below the fundamental absorption edge

“…It should be noted that similar high-order nonlinearlities have been observed in ZnSe-based semiconductors. 8,9 The finding of optical nonlinearlity at the transparent energy range is interesting not only from the physics viewpoint but also from applications related to the high-speed multisignal processing with low optical conditions.…”
