Caltech Chip Steers Light in Just 74 Femtoseconds
A new nanoengineered silicon surface lets one laser beam redirect another almost instantly, clearing a speed limit that has capped optical computing for decades.
Technology
Tiny 'Rainbow Chip' Could Supercharge 6G Networks
A microchip the size of a grain of rice generates a precise rainbow of light frequencies — a potential key to unlocking the ultra-fast millimeter waves needed for 6G wireless networks.
Technology
Monash Builds First Chip That Generates, Steers and Reads Light in One Device
A single Monash University chip can now generate, route and read information carried by light — solving a stubborn obstacle that has held back the field of valleytronics for years.
Technology
A New Crystal Could Make Ultrathin AR Glasses and Smart Contacts Real
Scientists have mapped a layered crystal that bends light more strongly than any material before measured, opening a path to genuinely slim AR glasses and smart contact lenses.
Technology
Monash Builds a Tiny Chip That Computes With Light, Not Electricity
Australian researchers have packed multiple optical functions onto a single chip, opening a path to faster, lower-power computing — and quantum-inspired tech that runs at room temperature.
Technology
Stanford's Fingertip-Sized Chip Boosts Light 100x With Tiny Power Draw
A new Stanford optical amplifier the size of a fingertip can intensify light signals 100-fold on a few hundred milliwatts — small enough to run on a battery and fit inside a smartphone.

Photon Teleported Between Quantum Dots Across 270 Meters
A European team beamed a photon's quantum state between two separate quantum dots over a 270-metre free-space link — a real step toward a quantum internet.
Science
New Camera Captures Events Unfolding in Trillionths of a Second
Chinese researchers unveiled an imaging method that captures both brightness and structural change in a single shot at femtosecond speeds — opening a new window on ultrafast science.
Technology
Scientists Shatter the Solar Cell Efficiency Ceiling with a 130% Quantum Yield
A team from Kyushu University and Johannes Gutenberg University achieved what was long thought impossible — extracting more energy carriers from sunlight than photons absorbed.
Science
Duke Engineers Build the Fastest Light Detector Ever — and It Needs No Power to Run
A new ultrathin photodetector from Duke University captures light across the entire electromagnetic spectrum in just 125 picoseconds, opening doors to revolutionary cameras for medicine and agriculture.
