Abstract

Nonreciprocal phase biases were experimentally investigated in a single-mode fiber-optic Sagnac type gyro with nonsingle-mode spatial filters. A good correlation between the nonreciprocal phase biases in the fiber-optic ring interferometer and the intensities of the higher order core modes and cladding modes in the fibers used as spatial filters was obtained. A new experimental method for determination of the optimum spectral range between the source wavelength in the gyro and the effective cutoff wavelength of the single-mode spatial filter was proposed.
