Abstract: We report a systematic study of free-space terahertz (THz) emission from photoconductive antennas (PCAs) nanodecorated with gold nanoparticles (Au-NPs) deposited by using the pulsed laser deposition (PLD) technique. H-shaped dipole micro-structured PCAs fabricated on semi-insulating… read more here.

Abstract: To theoretically predict the peak frequencies of terahertz (THz) electromagnetic radiation generated by photoconductive antennas, we have calculated the peak frequency of THz waves from laser-induced plasma. The peak frequency is the frequency with the… read more here.

Abstract: We present a telecommunication-compatible frequency-domain terahertz spectroscopy system realized by novel photoconductive antennas without using short-carrier-lifetime photoconductors. Built on a high-mobility InGaAs photoactive layer, these photoconductive antennas are designed with plasmonics-enhanced contact electrodes to achieve… read more here.
