Direct optoelectronic generation and detection of sub-ps-electrical pulses on sub-mm-coaxial transmission lines
(AIP Publishing, 2004-12-20)
We report efficient direct optoelectronic generation of sub-ps-THz pulses on 50 Ohm coaxial transmission lines with a 330 micro-m diameter solid copper outer tube filled with Teflon containing the 80 micro-m diameter inner ...
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 ...
Planar THz quasioptics
(AIP Publishing, 2004-08-09)
Two-dimensional (2D) quasioptical elements are demonstrated as guiding structures in the THz frequency regime. A planar polyethylene lens is incorporated in a parallel metal plate structure and is shown to focus guided THz ...
