Optical nonlinearities in quantum confined semiconductor microcrystallites in glasses

Open Access Open Access

Abstract

We review the main aspects of the light and electric field-induced refractive index and absorption changes in quantum confined semiconductor microcrystallites in glasses. In microcrystallites of a radius smaller than the electron radius the quantum size effects lead to drastic modifications of the electron and hole states and their dynamics. This is in particular reflected in a quantum size enhancement of the optical Kerr coefficient.
