Abstract

A wideband design is proposed for nonreciprocal phase shift magneto-optical isolators based on Mach–Zehnder interferometers. The wavelength dependence of nonreciprocal phase difference between the backward waves propagating in two interferometer arms is compensated for by that of reciprocal phase difference. This is realized by introducing an appropriate phase bias in one of interferometer arms. Two design examples are presented with a backward loss of >30dB in the wavelength range of 1.401.63μm for a magnetic garnet waveguide isolator and of 1.4851.630μm for a Si-wire waveguide isolator.
