摘要：
A planar Fabry-Perot cavity with intermirror spacing of d << lambda is explored for its "zero-order mode" terahertz transmission. The enhanced transmission observed as d -> 0 indicates that such cavities satisfy the resonance conditions 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.
