Observation of a new type of THz resonance of surface plasmons propagating on metal-film hole arrays
(American Physical Society, 2004-11-04)
Highly conducting metal-film subwavelength hole arrays, lithographically fabricated on high-resistivity silicon wafers in optical contact with thick silicon plates, have been characterized by terahertz time-domain spectroscopy ...
Integrated waveguide-coupled terahertz microcavity resonators
(AIP Publishing, 2007-11-09)
We demonstrate integrated square terahertz microcavity resonators side coupled to waveguides. We present the microcavity transmission spectra for different resonator sizes and coupling strengths. The measured quality factors ...
Adiabatic compression of terahertz waves using metal flares
(AIP Publishing, 2010-05-14)
We report on the adiabatic free-space coupling of broadband terahertz (THz) radiation through a subwavelength gap using metal flares. Amplitude coupling ratios better than 30% are obtained by optimizing the curvature. This ...
