Global optimization of optical metasurfaces using the RCWA method [PDF]

, 2023
A metaatom is a nanoparticle that interacts with light such that it creates a phaseshift. Through using these metaatoms as building blocks, one may create a metasurface.

Ultra-Thin and Lithography-Free Transmissive Color Filter Based on Doped Indium Gallium Zinc Oxide with High Performance

Micromachines, 2022
A kind of ultra-thin transmissive color filter based on a metal-semiconductor-metal (MSM) structure is proposed. The displayed color can cover the entire visible range and switches after H2 treatment. An indium gallium zinc oxide (IGZO) semiconductor was

Tailoring the Optical Transmission Spectra of Double-Layered Compound Metallic Gratings

IEEE Photonics Journal, 2013
The transmission resonance characteristics of a gold double-layered compound grating (DCG) are investigated numerically using the rigorous coupled-wave analysis (RCWA) method. The DCG is assumed to comprise two identical single-layered gratings separated

A Theoretical Description of Node-Aligned Resonant Waveguide Gratings

Optics, 2022
Waveguide gratings are used for applications such as guided-mode resonance filters and fiber-to-chip couplers. A waveguide grating typically consists of a stack of a single-mode slab waveguide and a grating. The filling factor of the grating with respect

Single Chip-Based Nano-Optomechanical Accelerometer Based on Subwavelength Grating Pair and Rotated Serpentine Springs

Sensors, 2018
Optical coupling between subwavelength grating pairs allows for the precise measurement of lateral or vertical displacement of grating elements and gives rise to different types of displacement and inertial sensors. In this paper, we demonstrate a design

Diffraction grating theory with RCWA or the C method [PDF]

, 2004
Diffraction gratings are often used in optical metrology. When an electromagnetic wave is incident on a grating, the periodicity of the grating causes amultiplicity of diffraction orders.
