Abstract :
Summary form only given. The development of the THz frequency band has opened up new opportunities for signal processing at ultrahigh speed using THz pulses. Recently we have demonstrated an optoelectronic modulator device operating at 3 THz. In this contribution, we report on the analog differentiation of THz pulses in time domain. Time-resolved THz experiments show that grating couplers can be designed to have a transmitted signal that is the time derivative of the incident THz pulses. The experimental results are compared to both classical and quantum mechanical calculations of the transmission function.
