Photoconductive generation and detection of THz-bandwidth pulses using near-field coupling to a free-space metallic slit waveguide. Optics Express, 25(22), 26492-26499. DOI: 10.1364/OE.25.026492https://doi.org/10.1364/OE.25.026492http://hdl.handle.net/1828/10603THz-bandwidth pulses are generated, transmitted along a gold-plated stainless steel metallic slit waveguide, and detected with 1.5 THz bandwidth and 60 dB dynamic range. The source and detector were edge-pumped slotlines on LT-GaAs placed within the near-field region of the waveguide entrance and exit aperture. The motivation for this work was to develop a complete dispersion-free THz system which was simple to manufacture and could be utilized for free-space waveguide experimentation.enArticleDepartment of Electrical and Computer Engineering
