Polarization-based branch selection of bound states in the continuum in dielectric waveguide modes anti-crossed by a metal grating

open access: yesNew Journal of Physics, 2019
We investigate bound states in the continuum (BICs) in a planar dielectric waveguide structure consisting of a gold grating on a dielectric layer with a back layer of metal.

Experiment and Simulation of a Selective Subwavelength Filter with a Low Index Contrast

open access: yesNanomaterials, 2019
Subwavelength gratings have been of great interest recently due to their ability to eliminate multiple orders. However, high index contrast ( Δ n ∼ 3 ) is typically achieved using metals or high-index dielectrics surrounded by vacuum in ...

Laser Interferometry for Broad Area SPR-Grating Couplers in Chemical Applications

open access: yesProceedings, 2017
In this work, the fabrication of a SPR (Surface Plasmon Resonance)-grating coupler using Laser Interference Lithography (LIL) has been investigated, giving rise to large area diffraction gratings on a 100 nm-thick gold film. The period of the diffraction

Flow-regulating mechanisms of gratings and their design implications in lateral-intake multiple forebays

open access: yesEngineering Applications of Computational Fluid Mechanics
Lateral-intake multiple forebays, widely used in large urban water supply pumping stations, are prone to undesired flow patterns such as recirculation, helical flow and vortices due to lateral inflow and limited space, necessitating flow-regulating ...

Nanoimprint on Silicon for Opto-Electronic Applications

open access: yesMicro
For the development of a novel optical sensor technology, diffraction grating microstructures were manufactured on a silicon surface. The principle of operation of the sensor technology is based on rotatory encoder technology, developed at Hahn-Schickard.

Freestanding HfO2 grating fabricated by fast atom beam etching

open access: yesNanoscale Research Letters, 2011
We report here the fabrication of freestanding HfO2 grating by combining fast atom beam etching (FAB) of HfO2 film with dry etching of silicon substrate. HfO2 film is deposited onto silicon substrate by electron beam evaporator.
