论文摘要
我们利用半导体材料的光激发作为宽带Terahertz场的“反射率开关”。我们表明，对此开关的明智使用可以使THZ场的时间表征具有空间分辨率，从而显着超过了Terahertz的衍射极限，并为时空Terahertz光谱法提供了理想的手段。
We utilize the photoexcitation of a semiconductor material as a 'reflectivity switch' for a broadband terahertz field. We show that judicious use of this switch enables temporal characterization of the THz field with spatial resolution significantly surpassing the diffraction limit of the terahertz and provides desirable means for spatio-temporal terahertz spectroscopy.
