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 ...

Study of the dynamic formation of transmission gratings recorded in photopolymers and holographic polymer-dispersed liquid crystals [PDF]

, 2004
Local and nonlocal models for the diffusion of photopolymers are applied to the dynamic formation of transmission gratings recorded in photopolymers and holographic polymer-dispersed liquid crystals (H-PDLCs). We retrieve the main parameters of H-PDLCs (
