Polarization control in optical-fiber gyroscopes.
TL;DR: It is shown that the maximum drift rate that is due to faulty polarization control is proportional to the amplitude-extinction ratio for the rejected polarization channel, and in the worst circumstances, the intensity extinction in a typical fiber gyroscope must approach 10(-6).

Rotation-induced superstructure in slow-light waveguides with mode-degeneracy: optical gyroscopes with exponential sensitivity
TL;DR: In this paper, a rotation-dependent stop band is formed in the center of the slow-light waveguide transmission curve, and a light signal of frequency within this stop band that is excited in a finite-length section of such a waveguide decays exponentially with the rotation speed and with the coupled resonator optical waveguide's total length or total number of degenerate microcavities.
