Abstract
A fiber optic interferometer provides Kerr effect compensation by intensity modulating counterpropagating waves of unequal intensity such that the average value of the square of the intensity is equal to a constant times the average value of the intensity squared, the constant preferably being equal to about two. The intensity modulation may be achieved by using a modulator in combination with a light source or by using a source in which plural frequencies combine to provide the modulation.
