Parallel Computing for Application in Rigorous Coupled-Wave Analysis

2012 Fifth International Symposium on Computational Intelligence and Design, 2012
The rigorous coupled-wave analysis of two-dimensional gratings is revived. Parallel computing method is introduced in the codes based on RCWA. Hybrid computation using GPU with CPU is used to improve the efficiency of the RCWA simulation program, There are combination of highly parallel computing ability of GPU, and the fast serial computing ability of

Rigorous coupled-wave analysis of photorefractive reflection gratings

Journal of the Optical Society of America B, 1998
Rigorous coupled-wave reflection grating analysis and Kukhtarev’s equations have been solved in the time domain to determine the optical intensity, electron density, and dielectric modulation in BaTiO3. A novel Green’s-function approach has been developed to analyze Kukhtarev’s material equations.

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.

Rigorous coupled wave analysis of grating coupled surface-emitting guided-wave devices

Optics in Computing, 2003
An extremely efficient rigorous vector electromagnetic analysis of grating-coupled surface-emitting lasers (GCSEL) is developed by constructing an artificially periodic structure with the GCSEL device as its unit cell and utilizing the rigorous coupled wave approach for the analysis of grating diffraction.

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

Review and Applications of Rigorous Coupled-Wave Analysis of Grating Diffraction

Diffractive Optics: Design, Fabrication, and Applications, 1992
The diffraction of electromagnetic waves by periodic structures continues to be of great interest and practical importance owing to numerous applications in a variety of fields such as acousto-optics, electro­optics, integrated optics, spectroscopy, optical computing, optical interconnects, and quantum electronics. Optical gratings may be planar (slab,

Structuring the incident and transmitted regions in rigorous coupled-wave analysis

2016 15th Workshop on Information Optics (WIO), 2016
We adapt the common rigorous coupled-wave analysis (RCWA) to the treatment of structured incident and transmitted regions. This algorithm is applicable to simulate waveguides, fibers, integrated optical components, or generally all situations where the influence of distant interfaces needs to be neglected.

Rigorous coupled-wave analysis of metallic surface-relief gratings

Journal of the Optical Society of America A, 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.

Two-sided illumination in rigorous coupled-wave analysis applied to the 4π-microscope

Journal of the Optical Society of America A, 2017
We apply the rigorous coupled-wave analysis (RCWA) to the simulation of 4π-microscopy. To achieve this, the concept of structured illumination [J. Opt. Soc. Am. A31, 2385 (2014)JOAOD60740-323210.1364/JOSAA.31.002385] is combined with the idea of coherent two-sided light incidence. We show how the latter can be integrated into the framework of the RCWA.

Rigorous coupled-wave analysis for lamellar grating with period modulation

2013 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2013
This paper considers the electromagnetic scattering problem of a lamellar grating with period modulation, and presents a formulation based on the rigorous coupled-wave analysis (RCWA). The RCWA is originally developed to analyze the plane-wave scattering from perfectly periodic structures, and uses the pseudo-periodic property of the fields.
