Abstract

We present a numerical investigation of terahertz channel plasmon polaritons (CPPs) propagating in a semiconductor InSb. It is shown that these CPPs can simultaneously exhibit subwavelength field confinement and relatively long propagation length. Moreover, single-mode propagation is available for terahertz CPPs in a certain frequency range.

摘要

我们对在半导体锑化铟中传播的太赫兹沟道表面等离激元极化激元（CPPs）进行了数值研究。结果表明，这些CPPs能够同时展现出亚波长场限制和相对较长的传播长度。此外，太赫兹CPPs在特定频率范围内可实现单模传播。
