Enhancement of Photodetector Responsivity in Standard SOI CMOS Processes by introducing Resonant Grating Structures [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 A new photodetector concept is described, which is fully compatible with the standard SOI CMOS process and does not require any post-processing steps. Our simulations are based on two-dimensional RCWA (Rigorous Coupled Wave Analysis) and local absorption

Coupled-mode theory for resonant gratings with a varying period
Компьютерная оптика, 2023 We propose a coupled-mode theory for resonant diffraction gratings with a varying period. We consider diffractive structures, in which the reciprocal lattice vector, a quantity inversely proportional to the period, varies linearly in the direction of ...

Rigorous coupled-wave analysis of liquid crystal polarization gratings
Optics Express, 2020 Several types of liquid crystal polarization gratings (LCPGs) can be achieved depending on their molecular configurations and diffraction properties. We perform detailed numerical studies of these LCPGs based on the rigorous coupled-wave analysis (RCWA) approach.
