A research renaissance into chip-based control of light-sound interactions could transform our 5G networks, satellite communications and defense industries. These interactions, known as Brillouin scattering, are set to underpin new designs in microchips and push our theoretical understanding of fundamental science, write Professor Ben Eggleton and colleagues in Nature Photonics.
According to Adar Ovadya, a master's student in BGU's Department of Software and Information Systems Engineering, 'all of the routers we surveyed regardless of brand or price point were vulnerable to at least some cross-network communication once we used specially crafted network packets. A hardware-based solution seems to be the safest approach to guaranteeing isolation between secure and non-secure network devices.'
Engineers at the University of California San Diego have developed the thinnest optical device in the world -- a waveguide that is three layers of atoms thin. The work is a proof of concept for scaling down optical devices to sizes that are orders of magnitude smaller than today's devices. It could lead to the development of higher density, higher capacity photonic chips.
A recipe for creating a microscopic crystal structure that can hold 2 wavelengths of light at once is a step toward faster telecommunications and quantum computers.
Healthy and competitive markets -- and not stringent regulations -- help dial back the cost of mobile phone contacts, according to new research.
A US Army project exploring novel applications of superconducting resonators has discovered these systems may be used to simulate quantum materials impossible to otherwise fabricate. Additionally, they may provide insights to open and fundamental questions in quantum mechanics and gravity.
Development of nanocomposite material simultaneously possessing high stretchability, high conductivity, and self-healability. Investigation of self-boosting phenomenon that enables spontaneous increase in electrical conductivity (over 60 times greater than the initial value) when external tensile strain is applied.
An end-to-end transmitter-receiver created by engineers in UCI's Nanoscale Communication Integrated Circuits Labs, is a 4.4-millimeter-square silicon chip that is capable of processing digital signals with significantly greater speed and energy efficiency because of its unique digital-analog architecture.
A research team led by physicists at the University of California, Riverside, has observed, characterized, and controlled dark trions in a semiconductor -- ultraclean single-layer tungsten diselenide -- a feat that could increase the capacity and alter the form of information transmission.
UK researchers have developed world-leading Compound Semiconductor (CS) technology that can drive future high-speed data communications. A team from Cardiff University's Institute for Compound Semiconductors (ICS) worked with collaborators to innovate an ultrafast and highly sensitive 'avalanche photodiode' (APD) that creates less electronic 'noise' than its silicon rivals.
