Abstract

In this paper, we report a novel configuration of micro optic gyro (MOG), which is monolithically integrated on silica Planar Lightwave Circuit (PLC) with countermeasures for noise factors. Optical ring-resonator gyros suffer mainly form polarization fluctuation induced noise and backscattering induced noise. We adopt a stress applying amorphus silicon film as the countermeasure for the former, and binary phase shift keying (b-PSK) as the one for the latter. However, to apply b-PSK, thermo-optic (TO) phase modulation is the only one scheme available in silica waveguide, whose bandwidth is limited to approximately 1 KHz. To utilize the narrow bandwidth of the TO modulator effectively, we propose an electrical signal processing scheme and frequency compensating modulation waveform. We demonstrate the suppression of the backscattering induced noise as 7.6dB. Additionally the gyro output is observed with applying an equivalent rotation.
