Derivation of Exponential Evanescent Field Beyond the Turning Point of Planar Optical Waveguides
In the region beyond the turning point at the substrate side of graded-index planar optical waveguides,it is shown that the field solution is a rigorous exponential evanescent function.The attenuated coefficient can be characterized by an equivalent refractive index.
