The use of broad-band sources, polarized and unpolarized, in fiber gyroscopes with linearly birefringent fibers, is studied theoretically. Polarization-mode coupling the modeled using one-mode center. Gyroscope output equations are obtained which useful interpreting an origin noise limiting cases low high birefringence. Interference effects shown to be related mode at particular locations fiber. extent these governed by a depolarization length for numerical estimates given.
