Graphene based terahertz absorbers

Graphene Flagship researches from CNR-Istituto Nanoscienze, Italy and the University of Cambridge, UK have shown that it is possible to create a terahertz saturable absorber using graphene produced by liquid phase exfoliation ...

Quantum dots offer new platform for fingertip terahertz devices

Scientists from Russia and the U.K. have developed an antenna that can aid in reducing sources of terahertz radiation down to the size of a fingertip. The antenna is a "sandwich" of semiconductor layers combined with quantum ...

Building a bright future for lasers

Invisible to the human eye, terahertz electromagnetic waves can "see through" everything from fog and clouds to wood and masonry—an attribute that holds great promise for astrophysics research, detecting concealed explosives ...

Graphene plasmons used to create tunable terahertz laser

(Phys.org)—A team of researchers working at the University of Manchester in the U.K has developed a tunable teraherz laser using the unique properties of graphene plasmons. In their paper published in the journal Science, ...

Researchers develop 'metasurface' laser for terahertz range

Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have identified a new way to make a semiconductor laser that operates at terahertz frequencies. The breakthrough could lead to development of ...
