Generalized optical transfer-matrix technique: application to the nonlinear response of multiple quantum wells

Abstract

A theoretical study of the electromagnetic field inside a multiple-quantum-well (MQW) structure possessing a quadratic optical nonlinearity is undertaken. The nonlocal response of each quantum well of the structure is analyzed on the basis of the integral equation for the local field inside the well. The light propagation inside the structure at the fundamental and sum frequencies is described within the generalized transfer-matrix technique. An application of the developed technique to calculation of the optical response of a model MQW structure is demonstrated.
