Résumé

We demonstrate the construction of corrugated waveguides using stacked rings to propagate terahertz frequencies. The waveguide allows propagation of the same fundamental mode as an optical-fiber, namely, the H E11 mode. This simple concept opens the way for corrugated wave-guides up to several terahertz, maintaining beam characteristics as for terahertz applications.

Térahertz

La bande de fréquences térahertz désigne les ondes électromagnétiques s'étendant de (ou selon les références) à . Elle est intermédiaire entre les fréquences micro-ondes et les fréquences correspondant à l'infrarouge. Le domaine des fréquences « térahertz » (THz, 1 THz = 10 Hz) s'étend de à 30 THz environ, soit environ aux longueurs d'onde entre et . Il est historiquement connu sous la terminologie d'infrarouge lointain mais on le retrouve également aujourd'hui sous l'appellation de rayon T.

Terahertz metamaterial

A terahertz metamaterial is a class of composite metamaterials designed to interact at terahertz (THz) frequencies. The terahertz frequency range used in materials research is usually defined as 0.1 to 10 THz. This bandwidth is also known as the terahertz gap because it is noticeably underutilized. This is because terahertz waves are electromagnetic waves with frequencies higher than microwaves but lower than infrared radiation and visible light.

Single-mode optical fiber

In fiber-optic communication, a single-mode optical fiber (SMF), also known as fundamental- or mono-mode, is an optical fiber designed to carry only a single mode of light - the transverse mode. Modes are the possible solutions of the Helmholtz equation for waves, which is obtained by combining Maxwell's equations and the boundary conditions. These modes define the way the wave travels through space, i.e. how the wave is distributed in space. Waves can have the same mode but have different frequencies.
