Optical Biasing of Ring Laser Gyroscope by Quantum Well Mirror,

Abstract

The Quantum Well Mirror (QWM) is a semiconductor device fabricated from AlGaAs/AlAs. It is composed of two structures, a back surface mirror and a front filter. The purpose of the QWM is to optically bias the ring gyroscope (RLG) out of the lock-in region. This is accomplished by shifting the apparent plane of reflection within the QWM by applying a voltage to the electrodes which control the optical filter. This device will reduce cost of the RLG by Removal of the mechanical dither hinge assemblies Removal of the high voltage circuitry used to drive the dither hinge Removal of the path length controller assemblies. Loosening of the performance requirement for the inertial sensor assembly (ISA) shock mounts. Increased reliability resulting from the removal of all mechanical assemblies in the RLG system.
