We introduce and present general properties of hybrid terahertz waveguides. Weakly confined Zenneck waves on a metal-dielectric interface at terahertz frequencies can be transformed to a strongly confined yet low-loss subwavelength mode through coupling with a photonic mode of a nearby high-index dielectric strip. We analyze confinement, attenuation, and dispersion properties of this mode. The proposed design is suitable for planar integration and allows easy fabrication on chip scale. The superior waveguiding properties at terahertz frequencies could enable the hybrid terahertz waveguides as building blocks for terahertz integrated circuits.
我们介绍并阐述了混合太赫兹波导的一般特性。太赫兹频率下金属 - 电介质界面上的弱受限曾内克波可以通过与附近高折射率电介质条的光子模式耦合，转变为强受限且低损耗的亚波长模式。我们分析了这种模式的限制、衰减和色散特性。所提出的设计适用于平面集成，并且能够在芯片规模上轻松制造。太赫兹频率下卓越的波导特性可使混合太赫兹波导成为太赫兹集成电路的构建模块。
