Diffraction efficiency of gratings with sinusoidal profile
Original language description
The aim of this study is to compare the diffraction efficiency of a sinusoidal diffraction grating numerically calculated using COMSOL with the measured results performed with a custom-made equipment and calculations using Bessel functions. A diffraction grating with the period of 860 nm and thickness of approximately 120-140 nm was prepared by hot embossing in As20Se80 layer. The custom-made equipment consists of a laser LED diode source, a rotation sample stage with independent adjustment of angle of incidence/diffraction angle, and a photodiode detector. The calculated diffraction efficiency using Bessel functions agrees satisfactorily with the measured results. Firstly, results obtained by utilization of Plasmonic Wire Grating application using COMSOL will be compared with previous results. As a next step, simulation using Wave optics COMSOL module will be performed in order to assess the effect of the grating profile and thickness on modeled as well as measured results.
