ABSTRACT:
A passive ring resonator gyro is constructed of an electromagnetic waveguide ring path which causes a specified rotation of the polarization of the waves, once for each round trip through the ring path. For an optical fiber ring path, a splice at some point is introduced in the ring path in which the fiber ends are rotated relative to each other in order to effect polarization rotation.
