Paper Abstract

Two major error sources associated with the scale-factor linearity of serrodyne closed-loop1,2 fiber-optic gyroscope are the stability of light source wavelength, and the perfection of loop-closure compo-nents and the associated driving electronics. LiNbO3 phase modulators3,4,5 are currently the most promising devices as the loop-closure component due to their wide bandwidth, large modulation index, and baseband operation. However, the non-ideal serrodyne driv-ing waveform, and the undesired amplitude modulation effects of LiNbO3 phase modulator, result in multiple sideband generations which limit the scale-factor linearity of serrodyne closed-loop fiber-optic gyroscopes.
