摘要
We report on the detection of weak terahertz pulsed signals, generated by either a commercial photoconductive antenna or an electro-optic crystal pumped by femtosecond laser pulses, using high-sensitive kinetic inductance detectors. Average powers as low as 0.1 fW have been recorded. We observe an unexpected constant signal when the bias voltage of the photoconductive antenna is strongly reduced.
