摘要:

本文研究了一种平面法布里-珀罗腔,其镜面间距显著短于探测波长,并探索其“零阶模式”太赫兹透射特性。当镜面间距d趋近于0时观察到的增强透射表明,此类腔体在宽太赫兹带宽内满足共振条件。利用时域太赫兹光谱技术,实验证实了这一难以实现且“技术上具有挑战性”的区域的信号特征,并通过数值计算加以补充。这些结果为太赫兹场调制带来了引人注目的可能性,并为同时强耦合多个跃迁频率开辟了新途径。

英文摘要:

A planar Fabry-Perot cavity with inter-mirror spacing significantly shorter than the probing wavelength is explored for its "zero-order mode" terahertz transmission. The enhanced transmission observed as d approaches 0 indicates that such cavities satisfy the resonance condition across a broad terahertz bandwidth. The experimental signatures from this elusive, "technically challenging" regime are evidenced using time-domain terahertz spectroscopy and are complemented by numerical calculations. The results raise intriguing possibilities for terahertz field modulation and pave new paths for strong coupling of multiple transition frequencies simultaneously.
