Abstract
The authors propose a method that uses ternary phase shift keying modulation to eliminate backscattering-induced noise in a resonator micro-optic gyro (R-MOG) integrated onto a silica planar lightwave circuit (PLC). Ternary modulation overcomes limitations on the degree of elimination possible caused by the narrow bandwidth of the thermo-optic phase modulator on PLC, the bandwidth of which is limited to 1 kHz.
