TREATING AND/OR STABILIZING GASES IN OPTICAL GYRO BASED ON INORGANIC WAVEGUIDE

摘要

PROBLEM TO BE SOLVED: To provide a high performance gyroscopic system using a highly stable modulator. ! SOLUTION: An interference fiber optic gyroscope (IFOG) system 12 includes integrated optical circuit (IOC) 110 formed from an inorganic material that is treated with a first selected gas 223 and positioned in a sealed enclosure 222 filled with a second selected gas 221. The IOC 110 is a phase modulator 110 supported on a support structure 254. The support structure 254 is configured to couple light between the IOC 110 and other multiple components. !
