Calculation of efficiency of the coupling gratings with complicated profiles

The purpose of this work is an analytical description of fields of radiating mode and waveguide mode of the planar optical waveguide in coupling gratings with voluntary profile of grooves U(x,z). We have compared two types of coupling gratings: parallelogramic and rectangular. For calculation we hav...

Description
Summary:The purpose of this work is an analytical description of fields of radiating mode and waveguide mode of the planar optical waveguide in coupling gratings with voluntary profile of grooves U(x,z). We have compared two types of coupling gratings: parallelogramic and rectangular. For calculation we have used the amplitude profile of TE/sub 0/ mode. The efficiency of the CG with complicated profiles is calculated.
