Abstract
Recently an optical isolator was reported in InP/InGaAsP, using the magneto-optic effect in an SOA with a ferromagnetic contact. Through the nonreciprocal absorption in the presence of a lateral magnetic field it achieved 4dB isolation. Here a proposal is presented to improve on this performance, by combining non-reciprocal refraction and absorption. It uses the different influence on TE and TM of these effects. With polarization converters, which can be made with very high conversion efficiency, this can be exploited to give 20dB isolation, according to our analysis. A polarization diversity configuration can be applied to obtain polarization independence.
