Abstract
It is shown that light sources of low coherence will exhibit intensity fluctuations similar to those of thermal light, at least after traveling through a fiber with material dispersion. These fluctuation yield a vanishing intensity-dependent nonreciprocal phase shift for fiber gyroscopes.Keywords
