The future of wireless communications technology is fast advancing. It was only in 2019 that global operators started launching 5G. While 5G is still in the process of global implementation, 6G has ...

One potential application is in terahertz (THz) devices. Semiconductors can only absorb photons with energy greater than their energy gap, which typically rules out the THz frequency range. According ...

For example, a semiconductor has a small ‘energy gap’: it is an insulator in which ... in detecting and generating light in the terahertz (THz) frequency range 4, which could be useful in ...

A team of researchers from the University of Ottawa has developed innovative methods to enhance frequency conversion of terahertz (THz) waves in graphene-based structures, unlocking new potential for ...

A team of researchers from the University of Ottawa has developed innovative methods to enhance frequency conversion of terahertz (THz ... effectively bridging the gap between GHz electronics ...

“We need to be more forceful about emissions reductions,” Visioni said. “We have to bridge a gap. But we should work to prevent warming of the planet through other means. Cloud brightening, ...

The potential to develop graphene-based plasmonic nanoantenna arrays and transceivers, combined with the capability of transmitting nanocommunication pulses at terahertz (THz) frequencies—bridging the ...

As a promising next-generation network architecture, cell-free networks enable ultra-reliable connections and minimal fading/blockage, which are much favorable to the millimeter wave and terahertz ...

Until now, such light sources have traditionally relied on III-V materials, which are difficult and therefore expensive to integrate with silicon. This new laser addresses that gap, making it ...
