A Study of Beam Couplers for Integrated Optics
Abstract
The theoretical study of beam couplers that convert an optical beam into a guided surface wave, or vice-versa, has produced the following results: (1) A unified leaky-wave approach to beam couplers of the prism and grating varieties; (2) A procedure for beam shaping by varying the parameters of the guiding surface-wave structure; (3) A rigorous solution of scattering by dielectric gratings, which form the basis of grating couplers; (4) A demonstration of a novel directional blazing effect of surface waves by asymmetric gratings; (5) An approximate analysis of the properties of dielectric gratings, which has an accuracy that is adequate for their practical design; (6) The development of equivalent electric network for describing the coupling operation of dielectric grating, and (7) The formulation of simple criteria for the design and fabrication of such gratings.
