Hyperlens crystal is capable of viewing living cells at nanometer scale
29 Dec | LaserFocusWorldFull Text External Link Indicator
"An optical lens that can resolve features the size of a small virus on the surface of a living cell in its natural environment has been developed by a team of researchers led by Joshua Caldwell, associate professor of mechanical engineering at Vanderbilt University (Nashville, TN).1 The lens was made possible due to a fundamental advance in the quality of an optical material used in hyperlensing, a method of creating lenses that can resolve objects much smaller than the wavelength of light." by John Wallace

An Open-Source Smartphone Microscope
29 Dec | Optics & PhotonicsFull Text External Link Indicator
"A research team led by Wei-Chuan Shih from the University of Houston, USA, reports creating a multicolor fluorescence microscope from a smartphone and a 3-D printer—and they’ve made the computer-aided designs available online for free (Biomed. Opt. Express, doi: 10.1364/BOE.8.005075). The scientists say the smartphone microscope, outfitted with a 3-D inkjet-printed elastomer lens and a polylactic-acid (PLA) housing, could help equip researchers and healthcare providers in developing and rural areas, as well as hobbyists and backpackers, with imaging techniques for diagnostic functions, including detecting waterborne pathogens." by Sarah Michaud

Quantum-teleportation experiments turn 20
27 Dec | NatureFull Text External Link Indicator
"In 1997, it was demonstrated that quantum states can be teleported from one location to a distant one. The discovery had huge consequences for the development of quantum communication and computing. " Nicolas Gisin

Quantum computing: Quantum advantage deferred
27 Dec | Nature PhysicsFull Text External Link Indicator
"A type of optics experiment called a boson sampler could be among the easiest routes to demonstrating the power of quantum computers. But recent work shows that super-classical boson sampling may be a long way off." by Andrew M. Childs

Plasmonic hot carriers skip out in femtoseconds
26 Dec | Nature PhotonicsFull Text External Link Indicator
"Plasmonic antennas store energy by localizing light to nanoscale volumes. A plasmon’s oscillating electrons can scatter directly into a semiconductor, transferring the captured energy in less than ten femtoseconds." by S. K. Cushing

Large quantum systems tamed
26 Dec | NatureFull Text External Link Indicator
"Quantum-computing devices can be more powerful than their classical counterparts, but controlling large quantum systems is difficult. Two studies report work that overcomes this challenge." by Christine Muschik

Conformal metasurface coating eliminates crosstalk and shrinks waveguides
26 Dec | LaserFocusWorldFull Text External Link Indicator
"A team of electrical engineers at Penn State (State College, PA) has a way to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer metamaterial coating, each layer with a near-zero thickness and weight." by John Wallace

Inkjet-Printed Nanophotonics
19 Dec | IEEE SpectrumFull Text External Link Indicator
“Two-dimensional photonic-crystal cavities—optical nanocavities with strikingly high quality factors—form part of the bedrock of nanophotonics, serving in applications ranging from low-threshold lasers to single-photon sources to sensors. Recent advances in deep-UV photolithography have even raised the prospect of mass-producing high-quality photonic-crystal cavities using CMOS-compatible methods.” by Stewart Wills
