An interferometric fiber optic gyroscope having a wavelength-sensitive splitter which has a splitting ratio that changes according to light wavelength. A feedback circuit indicates any difference that there might be in the intensities of counterpropagating beams in the sensing loop of the gyroscope, and provides a signal to the light source to change the light wavelength in a direction to cause the splitter ratio to change so as to equalize the beams' intensities for eliminating the Kerr effect.
