Efficient three dimensional aperiodic rigorous coupled wave analysis technique

2011 13th International Conference on Transparent Optical Networks, 2011
The frequency-domain aperiodic rigorous coupled wave analysis method is used for the implementation of both the efficient two-dimensional mode solver and, including the advanced scattering matrix approaches, the three-dimensional propagation technique.

Conical diffractions of multilayered gratings modeled by Cartesian rigorous coupled-wave analysis

Journal of the Optical Society of America A, 2023
Rigorous coupled-wave analysis (RCWA) has become one of the most efficient electromagnetic solvers to cope with the diffractions of large-scale periodic nanostructures. Conventional RCWAs focus on planar diffractions and their iterative stabilities. Conical diffractions, as more general incidence cases, are paid little attention in developing their ...

Rigorous coupled-wave diffraction analysis of stratified volume photopolymer holograms

Diffractive Optics and Micro-Optics, 1998
Stratified volume holograms (SVHs) have been studied1,2 in the layered structures of holograms that are useful for several applications in optical communication such as an optical wavelength-selective filter. The hitherto investigation was performed by using the beam propagation method (BPM) to emulate the SVH with thin (Raman-Nath) gratings, taking ...

Algorithm for the rigorous coupled-wave analysis of grating diffraction

Journal of the Optical Society of America A, 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

Computation Improvement for the Rigorous Coupled-wave Analysis with GPU

2012 Fourth International Conference on Computational and Information Sciences, 2012
The rigorous coupled-wave analysis (RCWA) technique needs to obtain the exact solution of Maxwell's equations, a huge number of matrix operations may be involved in the process. The graphics process unit (GPU) has inherent advantage in large-scale parallel computation compared with CPU.

Numerical modeling of polarization gratings by rigorous coupled wave analysis

SPIE Proceedings, 2016
We report on the numerical analysis of polarization gratings (PGs) and study their general diffraction properties by using the Rigorous Coupled Wave Analysis (RCWA) method. With this semi-analytical method, we can perform rigorous simulation without paraxial approximation and have a complete understanding of diffraction behavior of PGs, including those

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

Journal of the Optical Society of America A, 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.

Numerical analysis of Bragg regime polarization gratings by rigorous coupled-wave analysis

SPIE Proceedings, 2017
We report on the numerical analysis of Bragg polarization gratings (PGs), especially those formed with liquid crystals, and study their general diffraction properties by Rigorous Coupled-Wave Analysis (RCWA). Different from traditional Bragg (isotropic) gratings, Bragg PGs are verified to have high diffraction efficiency for large field of view, which ...
