Applications of Metamaterials in Optical Waveguide Isolator

摘要

The utilization of metamaterials substrate in the structure of three-layer waveguide isolator has been presented. The guided dispersion characteristics of the optical waveguide isolator are numerically investigated for different values of the MTM substrate parameters. All calculations are done with the of the product of the permittivity and permeability of the MTM substrate kept constant at ε_sμ_s = 4.0. The result is then applied to the design of various nonreciprocal integrated-optical devices.
