Tunable "metasurface" is akin to optical swiss army knife
MIT engineers and colleagues report important new advances on a tunable metasurface, or flat optical device patterned with nanoscale structures, that they compare to a Swiss army knife while its passive predecessor can be thought of as just one tool,.....»»
Altermagnetism: A new type of magnetism, with broad implications for technology and research
There is now a new addition to the magnetic family: thanks to experiments at the Swiss Light Source SLS, researchers have proved the existence of altermagnetism. The experimental discovery of this new branch of magnetism is reported in Nature and sig.....»»
A "quantum leap" at room temperature: Ultra-low noise system achieves optical squeezing
In the realm of quantum mechanics, the ability to observe and control quantum phenomena at room temperature has long been elusive, especially on a large or "macroscopic" scale. Traditionally, such observations have been confined to environments near.....»»
A new optical metamaterial makes true one-way glass possible
A new approach has allowed researchers at Aalto University to create a kind of metamaterial that has so far been beyond the reach of existing technologies. Unlike natural materials, metamaterials and metasurfaces can be tailored to have specific elec.....»»
New InP-based modulator with record-high bit rates could help move more data faster
As data traffic continues to increase, there is a critical need for miniaturized optical transmitters and receivers that operate with high-order multi-level modulation formats and faster data transmission rates......»»
Another “patent troll” defeated by Cloudflare and its army of bounty seekers

Optical invention mirrors the image processing power of a human eye
On a cold, sunny day, you're driving on a rural road, surrounded by snow-covered fields. In an instant, your eyes process the scene, picking out individual objects to focus on—a stop sign, a barn—while the rest of the scene blurs in the periphery.....»»
Submonolayer biolasers: Lower gain, higher sensitivity
Designing sensitive and single-use biosensors for early diagnosis remains a major challenge. Scientists in China have invented submonolayer lasers on optical fibers as ultrasensitive and disposable biosensors......»»
Multi-dimensional multiplexing optical secret-sharing framework with cascaded liquid crystal holograms
Information security has become particularly crucial under the background of the big data era. Optical secret-sharing schemes encrypt information and physically divide it into different shares. Information can only be decrypted by cascading a suffici.....»»

Apple declares last MacBook Pro with an optical drive obsolete
The laptop hadn't been for sale in more than seven years. Enlarge / The 13-inch MacBook Pro from 2012. Sometimes, it's worth taking a moment to note the end of an era, even when that ending might have happened a long ti.....»»
Computer-designed proteins allow for tunable hydrogels that can form both inside and outside of cells
When researchers want to study how COVID makes us sick, or what diseases such as Alzheimer's do to the body, one approach is to look at what's happening inside individual cells. Researchers sometimes grow the cells in a 3D scaffold called a "hydrogel.....»»
A Trojan approach to guide and trap light beams via Lagrange points
Reliably guiding and capturing optical waves is central to the functioning of various contemporary technologies, including communication and information processing systems. The most conventional approach to guide light waves leverages the total inter.....»»
