Rigorous coupled wave analysis of induced photorefractive gratings

open access: yesProceedings of the IEEE, 1999
The usefulness of rigorous coupled wave theory in the analysis of induced transmission and reflection grating formation, wave mixing, and higher order generation is demonstrated. No approximations air made, exact photorefractive material equations are used, and optical and electrical anisotropies are included.

Rigorous coupled-wave analysis of planar-grating diffraction

Journal of the Optical Society of America, 1981
A rigorous coupled-wave approach is used to analyze diffraction by general planar gratings bounded by two different media. The grating fringes may have any orientation (slanted or unslanted) with respect to the grating surfaces. The analysis is based on a state-variables representation and results in a unifying, easily computer-implementable matrix ...

Algorithm for the rigorous coupled-wave analysis of grating diffraction

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 1994
Diffraction of light by periodic gratings is analyzed with a characteristic-matrix formalism based on a rigorous coupled-wave approach. This formalism is particularly convenient for modeling the diffraction by nonuniform periodic structures. In order to overcome numerical difficulties that are due to inhomogeneous eigenmodes, we propose a new algorithm

Rigorous coupled-wave analysis of pure reflection gratings

Journal of the Optical Society of America, 1983
Rigorous coupled-wave analysis is shown to be valid for a pure reflection grating The analysis is extended to take into consideration an arbitrary phase of the sinusoidal modulation of the pure reflection grating’s dielectric constant The correct method of computing the diffraction efficiencies is presented, and results obtained with the extended and ...

Efficient Implementation of Rigorous Coupled-Wave Analysis for Analyzing Binary Gratings

IEEE Antennas and Wireless Propagation Letters, 2020
In this letter, the conventional rigorous coupled-wave analysis method is improved by using the Cayley–Hamilton theorem. Using the proposed method, the forward and backward diffraction efficiencies of each order are solved directly from the eigenmatrix.

Rigorous coupled-wave analysis of metallic surface-relief gratings

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 1986
A rigorous coupled-wave analysis for metallic surface-relief gratings is presented. This approach allows an arbitrary complex permittivity to be used for the material and thus avoids the infinite conductivity (perfect-conductor) approximation. Both TE and TM polarizations and arbitrary angles of incidence are treated.

Algorithm based on rigorous coupled-wave analysis for diffractive optical element design

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 2001
Diffractive optical element design is an important problem for many applications and is usually achieved by the Gerchberg-Saxton or the Yang-Gu algorithm. These algorithms are formulated on the basis of monochromatic wave propagation and the far-field assumption, because the Fourier transform is used to model the wave propagation.

Localized input fields in rigorous coupled-wave analysis

Journal of the Optical Society of America A, 2014
We introduce a new treatment for localized input fields in coupled-wave theory. It consists of a combination of angular spectrum decomposition and a cyclic formulation of rigorous coupled-wave analysis (RCWA), which does not require the computation of several standard RCWA calculations.

Rigorous coupled-wave analysis for multilayered grating structures

SPIE Proceedings, 2003
A numerically stable and systematic implementation of the rigorous coupled-wave analysis (RCWA) for the general multilayered grating structures is presented for both TE and TM modes. Numerical results of the approach are shown for the diffraction-based optical device as an example and are compared with the scalar diffraction method to illustrate the ...
