Nonlinear Optical Interactions in Semiconductors
Abstract
They are in the process of completing two papers and four patents involving optical absorptions in GaAs which has led to the construction of a novel and highly sensitive optical temperature sensor. Another patent involving a liquid level sensor has become a by-product of the current research. They have studied two-photon optical pumping in semiconductors are continuing. Their attempts are focused on observing a number of new optical effects including nonlinear absorption and transmission phenomena, enhanced spontaneous and stimulated light scattering processes, etc. The construction of an external cavity semiconductor laser is completed. This will allow them to undertake a careful study of multiphoton optical pumping in semiconductors to generate IR radiation and a variety of studies involving narrow-gap semiconducting compounds outlined in their proposal. They 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. They have received the delivery of two large laser systems along with a variety of test and measurement equipment to enhance the current research under this contract. They have already utilized these lasers to explore elementary excitation in optical thin film layers of semiconductors. (rrh)
