FORMATION OF A SUPERRADIANT EXCITON-POLARITON MODE IN A GaN/AlGaN RESONANT BRAGG STRUCTURE

Abstract

The given work is devoted to studying the optical properties of the sample with of 30 GaN quantum wells separated by non-tunneling AlGaN barriers. Optical reflectance was studied at different angles of incidence for different polarization of the incident light at room temperature. A model has been verified that makes it possible to describe the experimental data and determine the parameters of excitons in quantum wells. This material system seems to be most promising for implementation of the concept into devices.
