Nonlinear Optical Interactions in Semiconductors
Abstract
Studies of multiphoton optical pumping in semiconductors are continuing in narrow gap semiconductors and in GaAs. Our attempts are focused on observing a number of new optical effects including non-linear absorption and transmission phenomena, enhanced spontaneous and stimulated light scattering processes, etc. The construction of an external ring cavity is currently near completion. This will allow us to undertake a careful study of multiphoton optical pumping in semi-conductors to generate IR radiation and a variety of studies involving narrow gap semiconducting compounds outlined in our proposal. We have studied the feasibility of room temperature operation of a tunable coherent source involving multiple quantum well material. An invention disclosure has been filed with the U.S. Air Force Patent Office for work performed on multiple quantum well material under this contract. We have also studied the absorption properties of a semiconductor under optical pumping with a white light source.
