Abstract
Considering the radius difference among layers and nonlinear temperature distribution inside the fiber coil, a simple, accurate model for the quantitative analysis of the thermal induced nonreciprocity in sagnac interferometer has been put forward and confirmed by experimental results. Based on the model, a novel approach to reduce the Shupe effect by 60% has been figured out.
