Researchers predict that a twisted graphene bilayer excited with light could host a slow-moving acoustic plasmon. Read More »
A single-layer transition-metal dichalcogenide on top of a silver film displays strong light–matter coupling without the need for nanostructures or microcavities. Read More »
A new observation of heat transport by surface waves involving electrons could lead to improved cooling strategies for microscale electronic components. Read More »
A waveguide sculpted in air with lasers transmits light over a distance of nearly 50 meters, which is 60 times farther than previous air-waveguide schemes. Read More »
An optical sensor consisting of gold nanorods can provide real-time data on insulin production in an on-chip device mimicking the pancreas. Read More »
A new waveguide design uses a series of apertures, or slits, to keep waves confined to a narrow path. Read More »
A nanoparticle can be made partially transparent by placing a molecule in front of it, forming a system that might work as an optical switch. Read More »
A thin film patterned with nanoantennas exhibits negative refraction of light, a useful feature for subwavelength imaging. Read More »
A new technique allows the capture and study of a single dust particle just 34 nanometers wide, nearly 10 times smaller than the previous limit. Read More »
The fragile quantum state of a pair of entangled photons can be protected when the photons pass through a nanoscale hole, which may be useful in future light-based computing. Read More »
