Black Phosphorus Enables Plasmonic Logic
22 Dec | IEEE SpectrumFull Text External Link Indicator
"Much research has been dedicated to exploiting the waves and oscillations of electrons that are produced on the surface of a metallic structure when photons of light strike it. These waves of electrons are called either surface plasmons when referring to the oscillations in charge alone, or surface plasmon polaritons when referring to both the charge oscillations and the electromagnetic wave. The field developed around exploiting this phenomenon has become known as plasmonics." by Dexter Johnson

Large Number of Atoms Trapped In an Array Bolsters Quantum Computing
10 Nov | IEEE SpectrumFull Text External Link Indicator
"Digital logic depends on bits. The binary states of “0” or “1” form the basis of computing. In quantum computers, the bit is replaced by something called a quantum bit (or, qubit), which is an atomic particle that can be coerced into being both 0 and 1 simultaneously, at least for a time." by Dexter Johnson
Graphene-Silicon Photodetector Could Enable the Internet of Things
19 Jul | IEEE SpectrumFull Text External Link Indicator
"While graphene has faced challenges in the field of digital logic because of its lack of an inherent band gap, it has been that very weakness that has attracted many researchers to exploring its use in optoelectronics. This lack of a band gap makes graphene an extreme broadband absorber, enabling photodetection for visible, infrared, and terahertz frequencies." by Dexter Johnson
Cybersecurity On Ships: New Guidelines

"Companies are becoming increasingly alive to the importance of cyber-security and the need to protect themselves against the risk of cyber-attacks; the marine sector is no exception, says Clyde & Co's Shipping Newsletter." by Aiswarya Lakshmi
Flexible Optical Metasurfaces Promise "Smart" Contact Lenses
11 Mar | IEEE SpectrumFull Text External Link Indicator
"The name of the game in optical metasurfaces is shortening the wavelengths of light. This yields devices that can manipulate light for information processing and also reduce the bulk of the devices based on traditional optics.

Metasurfaces have been pretty good at offering small, flat features, but the integrated metallic resonators they use to filter light according to specified frequencies have lacked efficiency. It was thought that dielectric resonators were an attractive alternative, but they present another problem: though fairly efficient, their frequency-filtering is hard to fine-tune.

Now researchers at RMIT University and the University of Adelaide have delivered the best of both worlds with a dielectric resonator that can be mechanically tuned. The property that makes these mechanically tunable dielectric resonators especially attractive is that they are embedded in a biocompatible polymer that renders them flexible." by Dexter Johnson
