Abstract

A mutual phase shift of two counterrotating optical waves in a coil is placed. For the given temperature field, an exact formula describing the total Sagnac phase shift of both the waves is derived in the paper. On the basis of this formula, all the temperature effects are discussed generally and in two special cases: in the linear and periodic temperature fields. At the end of the paper, two possibilites of thermal stabilization of the fiber coil are proposed and discussed.
