The investigation of THz generation using low-temperature-grown GaAs (LTG-GaAs) photoconductors integrated with horn antennas is reported. Results obtained using a photomixing experiment are presented. A maximum generated power of 1 muW at 780 GHz was achieved for an optical power of 2times80 mW and a photocurrent of 1 mA.
We have studied a new kind of terahertz antenna: transverse electromagnetic horn antennas (TEM-HA). These antennas have interesting characteristics for THz applications: large bandwidth, low reflection coefficient, good directivity and low dispersion. TEM-HA have been designed by simulation and measured thanks to a time-domain experiment. The reflection coefficient is less than -10 dB at frequencies...
