Abstract

A new method for polarization stabilization and prevention of polarization fade in fiber optic Michelson interferometers is presented. In contrast to previous techniques, the method is totally passive, does not utilize phase conjugation or other nonlinear optical effects, and requires no adjustments after initial setup. In addition, the method works independent of the amount and type of fiber and coupler birefringence, so that low-cost, ordinary optical fiber and couplers can be employed in this type of interferometer. This method also leads to a new kind of nonreciprocal effect sensor. The principles and theory of the effect are presented, as well as a particular stabilization scheme being implemented.
