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, ε_f. 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 ε_f = -8. The results are interesting since they assure the possibility to get maximum optimization of the isolator behavior by adding metallic materials.
