Frequency modulated lasers for interferometric optical gyroscopes

Tin Komljenovic, Minh A. Tran, Michael Belt, Sarat Gundavarapu, Daniel J. Blumenthal, and John E. Bowers

Abstract

We study the use of frequency modulated lasers in interferometric optical gyroscopes and show that by exploiting various frequency modulation signals, the laser coherence can be controlled. We show that both angle random walk and bias stability of an interferometric optical gyroscope based on laser sources can be improved with this technique.
