Paper Abstract

Narrow band resonant reflection of a polarized focused beam from a single-crystal silicon grid is demonstrated at terahertz frequencies with an efficiency close to 100 %. A spectral width of less than 7 μm at a resonance wavelength of 570 μm is achieved with a 4 mm-waist beam which overlaps with only ~10 grid periods. This compact reflection filter is a scale model of what can be expected at optical frequencies, but also represents a new type of compact terahertz device.
