A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open ...

A major bottleneck with high-frequency wireless communications is the conversion from radio frequencies to optical signals and vice versa. This is performed by an electro-optic modulator (EOM), which ...

A graphene-based material converts incoming terahertz pulses (from above) into visible light in an ultrafast and controllable manner - optimal for data transport in optical fibers. (Image: B. Schröder ...

Terahertz light holds enormous potential for tomorrow's technologies. It might succeed 5G by enabling extremely fast mobile communications connections and wireless networks. The bottleneck in the ...

When your business buys equipment that uses rays or lasers, the technical specifications may describe the wave in terms of frequency or wavelength. You can calculate either of these properties from ...

Terahertz technology enabled via graphene could boost the capacity of future data networks, according to researchers at Chalmers University of Technology in Sweden. Andrei Vorobiev, pictured, senior ...

Physicists at Bielefeld University and the Leibniz Institute for Solid State and Materials Research Dresden (IFW Dresden) have developed a method to control atomically thin semiconductors using ...

A new study has successfully demonstrated the confinement of terahertz (THz) light to nanoscale dimensions using a new type ...
