In this paper, we propose a concrete design for a Mach-Zehnder interferometer type isolator for TM modes. Just one of the arms, which are of equal length, is a nonreciprocal magneto-optic waveguide. The rest of the interferometer is reciprocal. Required fabrication tolerances are estimated, and the entire isolator is simulated by applying a finite difference beam propagation method. |
