Paper Abstract

The effect of a metal layer with negative permittivity on the behavior of nonlinear-magnetoopic isolator is studied. The isolator consists of Metal film, nonlinear cladding, and magnetooptic substrate. It is found that difference between forward and backward propagation for TM0 mode increases with increasing the absolute value of the tuning parameter which is the permittivity of the metal film, εf. It is also found that the maximum cutoff thickness of the isolator occurs in selfdefocusing case around η=0.65 and at the highest assumed value of εf = -8. The results are interesting since they assure the possibility to get maximum optimization of the isolator behavior by adding metallic materials.
