| Abstract: | The propagation constant and attenuation coefficient of the metal-clad graded-index planar optical waveguides were calculated with a new method combining the edge element method with the perturbation treatment.Some metal-clad waveguides with typical refractive index distributions were studied.Very good agreement was achieved between the numerical results obtained with the presented method and those given in the reference,justifying the validity,and proving the broad applicability of the method. |
