Problems solved by technology

Although the waveguide filter and high-fidelity structure of waveguide-coupled surface plasmons is a very mature technology in the visible light band, the corresponding systems working in the terahertz band are rarely reported, especially the high-fidelity and double-layer Ultra-wideband filters with waveguide structures have not been involved

Abstract

The invention provides a terahertz time-domain spectrum system based on an ultra-wideband chip. The system comprises a substrate and a metal layer. The metal layer is used for acquiring and conducting terahertz, and comprises a signal acquisition unit, a first mode switching part, a conducting part, a second mode switching part and a signal output part. The first mode switching part, the conducting part and the second mode switching part are of double waveguide structure. The signal acquisition part is used for acquiring the terahertz from a host device, and transmitting the terahertz to the first mode switching part for mode switching. The terahertz is changed into a surface wave. The surface wave is transmitted in the double waveguide of the conducting part, so as to form an energy band gap for filtering. The second mode switching part carries out mode switching again. The signal output part transmits the wave to a vector network analyzer for data analysis, so as to acquire the width of a band-pass band.

Description

technical field [0001] The invention belongs to the field of terahertz wave detection, and in particular relates to a terahertz wave time-domain spectrum system based on an ultra-wideband chip. Background technique [0002] With the development of modern wireless communication technology, ultra-wideband technology has received widespread attention in recent years. Modern communication products are widely used, and the frequency bands used by each product are different. To use these frequency bands simultaneously requires a wide-band transceiver system. [0003] Coplanar waveguide is an important means to realize broadband technology. It is actually surface plasmon resonance, which is a kind of charge density oscillation eigenmode existing at the interface of metal and dielectric, which can be excited by incident light through prism coupling, grating coupling or waveguide coupling. The ultra-wideband filter based on the double-layer structure of the coplanar waveguide reali...
