Abstract

Summary form only given. We present a novel device, a quarter-wave semiconductor mirror, which yields similar theoretical diffractive performance without the insertion loss associated with asymmetric Fabry Perot (ASFPs). A quarter-wave mirror operates in a high reflectivity region and does not require the careful control of surface quality and Fabry-Perot resonance placement necessary for the MQW ASFP. The device is similar in construction to stratified volume holographic optical elements except that it consists of alternating quarter-wave optical thickness layers of a nonabsorbing spacer and a photorefractive material.
