"Two research groups demonstrate the coherent interaction between the spin of a single electron and a single microwave photon." by R. Mark Wilson
ID Quantique partners with South Korean telecom giant on quantum technologies
05 Apr | LaserFocusWorldFull Text External Link Indicator
"ID Quantique (IDQ; Geneva, Switzerland) announced a strategic investment plan of $65 million from investor SK Telecom (Seoul, South Korea; NYSE:SKM), the South Korean telecom giant. The companies say the investment will strengthen ID Quantique's position as the global leader in quantum safe cryptography and quantum sensing solutions. It will also help IDQ to continue to develop global markets and partnerships in quantum technologies for the telecom and Internet of Things (IoT) markets." by Gail Overton

"Designer and manufacturer of optical thin-film coatings and heads-up displays Artemis Optical (Plympton, England) signed a three-year business development and technology partnership with Metamaterial Technologies (MTI; Dartmouth, Nova Scotia, Canada), a smart materials and photonics company, to develop a hybrid coating for the defense industry." by Gail Overton
'Weyl semimetal' shows larger nonlinear optical response than any other known crystal
03 Apr | LaserFocusWorldFull Text External Link Indicator
'Scientists at the University of California, Berkeley and Lawrence Berkeley National Laboratory (also in Berkeley) have experimentally discovered that a so-called Weyl semimetal, tantalum arsenide (TaAs), has the largest nonlinear optical response of any known crystal, achieving second-harmonic generation (SHG) of light with unprecedented response." by John Wallace
“Nanomushroom” Sensors Track Cell Growth
02 Apr | Optics and Photonics NewsFull Text External Link Indicator
“Medical researchers need ways to monitor, over long timescales, the proliferation of live cells used in laboratory drug tests and other clinical studies. But many assays for that purpose require complex labeling of cells with outside agents that hinder real-time monitoring over long periods. Now, a research team at the Okinawa Institute of Science and Technology (OIST) Graduate University, Japan, has created a label-free plasmonic biosensing material that can keep track of cell growth for as long as seven days—using an array of optical antennas shaped like tiny mushrooms (Adv. Biosyst., doi: 10.1002/adbi.201700258).” by Stewart Wills
Toward Dynamic Metalenses
02 Apr | Optics and Photonics NewsFull Text External Link Indicator
“Recent years have seen an explosion of research in flat optical components fashioned with so-called metasurfaces—intricately engineered, planar configurations of subwavelength elements. But most of these flat optical elements have lacked a means of active control, a drawback that’s held back their use in many applications.” by Stewart Wills
Noninvasive optical window created in the skull allows brain imaging
27 Mar | LaserFocusWorldFull Text External Link Indicator
“A noninvasive approach for creating an optical window in the skull to enable the brains of living mice to be imaged has been demonstrated at the Huazhong University of Science and Technology (Wuhan, China).1 Dan Zhu and her coworkers tested the use of optical clearing agents (OCAs) that they applied to the bare skulls (hair and skin removed) of living mice. After treatment with OCAs, the skull becomes transparent within minutes, thus forming a visible window of the cortex.” by John Wallace
