Analyzing Five-layer Planar Optical Waveguides with Kerr-type Nonlinear Metamaterial Guiding Films

摘要

In this paper, we proposed a method to analyze the electric field distributions of the five-layer planar optical waveguide structure with nonlinear metamaterial guiding films. The proposed nonlinear metamaterial planar optical waveguide is composed of two different kinds of media. One is the Kerr-type nonlinear metamaterial in the guiding films, and the other is the linear double-positive medium (DPS) in the interaction layer, in the cladding and in the substrate. We have derived the transcendental equations of the proposed five-layer planar optical nonlinear metamaterial waveguide structure. The propagation characteristics of the transverse electric (TE) waves were investigated analytically and numerically in the this structure. The analytical and numerical results show excellent agreement. The simulation results arc helpful to figure out the propagation situation of the TE polarized waves in the five-layer nonlinear metamaterial waveguide structure. The transverse magnetic (TM) polarized waves can also be predicted by the similar process. It can also be very useful for designing a planar nonlinear metamaterial waveguide devices.
