摘要

Femtosecond optoelectronic techniques are routinely employed for the generation and detection of ultrashort voltage pulses. However, so far, not much effort has been spent to determine the exact shape of such voltage pulses over a very broad frequency range. For this purpose, i.e., for the realization of a broadband voltage pulse standard, it is essential to (ⅰ) know the transfer function of the detection technique and (ⅱ) be able to separate forward and backward propagating signals from each other. Here we report the realization of a voltage pulse standard with frequency components exceeding 500 GHz and a 500 MHz frequency spacing.
