Description

technical field [0001] The invention relates to a terahertz photonic on-chip control system and a control method thereof, in particular to a terahertz photonic on-chip control system and a control method thereof utilizing surface plasmons. Background technique [0002] Terahertz (THz, 1THz=10 12 Hz) band usually refers to the frequency range from 100 GHz to 10 THz, the corresponding wavelength is from 3 mm to 30 microns, and the electromagnetic spectrum range is quite wide between millimeter wave (submillimeter wave) and infrared light. However, for a long time, due to the lack of effective terahertz sources and detection methods, electromagnetic waves in the terahertz frequency band have not been fully studied and applied, which is called the "terahertz gap" in the electromagnetic spectrum. The advancement of terahertz technology has provided a great freedom for people to characterize and manipulate matter. It has been widely used in radio astronomy detection, atmospheric ...

AI Technical Summary

Problems solved by technology

Although the generation, propagation and detection of terahertz waves have developed rapidly in the past ten years, the current standard terahertz test systems are still assembled and configured by individual components, requiring the use of relatively large and bulky far-field optics. Devices, especially the terahertz source, detection, propagation and modulation parts are separated in various places in the system, the physical distance between them is relatively large, and the integration level is quite low
