Resonator micro-optic gyro (RMOG) is a promising candidate for the next generation inertial rotation sensor based on the Sagnac effect. A current modulation technique used in an external cavity laser diode is proposed to construct the gyroscope system for the first time. The resonance curves before and after eliminating accompanying amplitude modulation are(More)
A photonic crystal ring resonator (PCRR) of air hole arrays is fabricated on a silicon-on-insulator wafer by using electron-beam lithography and inductively coupled plasma etching. The designed PCRR is modeled and its performance is simulated by the two-dimensional finite difference time domain method. The simulation results show that the PCRR has two(More)
A differential detection method (DDM) with a utility type and ease of realization for a micro-grating accelerometer is reported so as to reduce the common-mode noise and improve the sensitivity of the micro-grating accelerometer. The theoretical model is established, based on scalar diffraction theory for differential detection. According to the simulation(More)
The fiber ring resonator (FRR) is the key component of resonator fiber optic gyros (R-FOGs). The configuration of a novel hollow core photonic bandgap fiber (HC-PBF) ring resonator is proposed based on the usage of micro-optical structure. The normalized transfer function of such kind of FRR is derived, and the effects of different FRR parameters' on the(More)
