The terahertz band is, at least for now, somewhat of a spectrum oddity, positioned between microwaves and infrared light and roughly spanning from 0.1 THz (100 GHz/3 mm wavelength) to 10 THz (30 μm).

image: The image depicts a schematic of terahertz (THz) heterodyne detection with graphene. In this, two THz waves (red) are coupled into graphene, where they are combined or mixed.

Currently superconductors are used for Terahertz telescope detects but new graphene terahertz detectors will use less than 0.1% of the power. Instead of microwatts, the graphene detectors could use ...

Besides graphene nano-ribbons, further exploration will be made for new materials that can be used for radiation with frequencies from 0.5 THz to 5 THz. In the exploration, the wavelength of the ...

First practical application of viscous electron flow realizes terahertz photoconductivity in graphene. Story by Ingrid Fadelli • 1w. W hen light hits the surface of some materials, ...

Graphene-based saturable absorbers show strong potential for high-speed laser systems. Learn how integrating graphene with silicon photonics improves mode-locking and ultrafast pulse generation.

However, because of the unique properties of electromagnetic waves in the 0.1 to 10 THz range, it has proven difficult to develop high-performance components that showcase the true potential of THz ...
