摘要

我们提出了一种简单的方法来提高低成本太赫兹- qtds系统在带宽方面的性能。通过调制激光二极管的注入电流，提高了太赫兹信号的带宽。太赫兹频谱的滚降降低了55 dB/太赫兹。

Enhancement of THz-QTDS performance by pulsed laser operation

We present a straightforward method for enhancing the performance of a low-cost THz-QTDS system regarding the bandwidth. The bandwidth of the THz signal is improved by modulation of the injection current of the laser diode. The rolloff of the THz spectrum is decreased by 55 dB/THz.
