Flat silicon gradient index lens with deep reactive-ion-etched 3-layer anti-reflection structure for millimeter and submillimeter wavelengths
Fabien Defrance, Cecile Jung-Kubiak, John Gill +5
We present the design, fabrication, and characterization of a 100 mm diameter, flat, gradient-index (GRIN) lens fabricated with high-resistivity silicon, combined with a three-laye…
Flat low-loss silicon gradient index lens for millimeter and submillimeter wavelengths
Fabien Defrance, Cecile Jung-Kubiak, Sofia Rahiminejad +6
We present the design, simulation, and planned fabrication process of a flat high resistivity silicon gradient index (GRIN) lens for millimeter and submillimeter wavelengths with v…
A 1.6:1 Bandwidth Two-Layer Antireflection Structure for Silicon Matched to the 190-310 GHz Atmospheric Window
Fabien Defrance, Cecile Jung-Kubiak, Jack Sayers +7
Although high-resistivity, low-loss silicon is an excellent material for THz transmission optics, its high refractive index necessitates antireflection treatment. We fabricated a w…
Stacked Wafer Gradient Index Silicon Optics with Integral Anti-reflection Layers
F. Defrance, G. Chattopadhyay, J. Connors +8
Silicon optics with wide bandwidth anti-reflection (AR) coatings, made of multi-layer textured silicon surfaces, are developed for millimeter and submillimeter wavelengths. Single…
