我们报告的技术在太赫兹频率范围内的电介质材料的片上传感。我们表明，一个阵列的带阻滤波器，激发集成超快光电导开关，可用于感测电介质负载在一个芯片上的一些不同的光刻定义的位置同时，每个位置感测不同的太赫兹频率。该技术有望在片上太赫兹系统领域有一系列未来应用，如脱氧核糖核酸和其他分子膜的分析。
We report on a technique for the on-chip sensing of dielectric materials in the terahertz frequency range. We show that an array of band-stop filters, excited by integrated ultrafast photoconductive switches, can be used to sense dielectric loading at a number of distinct lithographically defined locations on a chip simultaneously, each location sensing a different terahertz frequency. This technique is expected to have a range of future applications in the field of on-chip terahertz systems, such as the analysis of deoxyribonucleic acid and other molecular films.
