Projects:2020s2-7153 High-efficiency planar waveguides for terahertz waves

Abstract

Terahertz integrated systems with high efficiency are important in a wide range of applications including terahertz communication, radar, imaging and sensing. This study advances the waveguide investigations by examining the dispersion, cross-polarization, and crosstalk, along with the characteristics of bends and crossings over the 220 to 330 GHz (WR-3 band) operating frequency range. To minimise substantial absorption of metals and dielectrics at terahertz frequencies, these self-supporting structures are built solely into a single silicon wafer.

Introduction

With a substantially growing proportion of the world's population accessing online services, data traffic has grown significantly. Most terahertz (THz) sources, however, are inaccessible, so designing efficient THz waveguides for versatile broadband THz radiation delivery is an important step towards terahertz techniques for practical applications. The terahertz spectrum that covers the frequency range from 0.1 to 10THz is an appropriate option for the support of the high-speed wireless sight transmission line by convergence electronics and optics. When used to connect the numerous THz point devices, such as sources, filters, sensor cells and detectors, THz waveguides can be very beneficial on system integration stage.
