Abstract :
A log-periodic antenna has been realised on LTG-GaAs (low-temperature-grown gallium arsenide) with an interdigitated photomixer for the generation of THz radiation. The signal is generated by optical heterodyning using the difference frequency of the lasers. The response is measured from 55 GHz up to 1200 GHz and compared with calculations. This approach leads to an optical modulation facility for THz communication of ultra broadband capability.
