Abstract
We report the prediction of the random walk coefficient of a solid-core single-mode polarization-maintaining photonic interferometer fiber optic gyroscope, a novel sensor that exhibits reduced thermal sensitivity owing to the stable temperature coefficient use of a photonic fiber. The random walk coefficient of the photonic interferometer fiber optic gyroscope is limited by detector thermal noise for detected powers under 1 μW and excess noise above 1 μW. Above this power level, the random walk coefficient is found to be independent of detected power and asymptotically to be 0.0029°/ \(\sqrt h \). This result is verified by the experiment.
