Analysis of deflecting characteristics for the deflection gratings on planar optical waveguide
The angular and frequency characteristics of deflection gratings on planar optical waveguide are discussed through evaluting the deflection efficiencies R obtained from the coupled mode equation. The analysis shows that these propertie in principle depend on the product | K | · L of the length L and the coupling coefficient |K| between incident and deflecting waves, rather than | K | or L individually.
