Abstract :
The characteristics of a waveguide optical isolator using a nonreciprocal phase shift are discussed. The isolator has the advantage of not needing phase-matching and complicated magnetization control. It is shown that the degradation of characteristics due to deviations in the waveguide parameters can be retained within acceptable limits by current technologies. Also, a rare earth iron garnet crystal suitable for constructing this isolator has been developed
