The speed record for data transmission using a single light source and optical chip has been shattered. Engineers have transmitted data at a blistering rate of 1.84 petabits per second (Pbit/s), almost twice the global internet traffic per second.
-
A powerful new optical chip can process almost two billion images per second. The device is made up of a neural network that processes information as light without needing components that slow down traditional computer chips, like memory.
-
A new type of radar can measure objects down to centimeters. The new technique uses a photonic system to generate much higher bandwidth signals, enabling radar that can detect smaller objects, and even monitor patient vital signs in hospitals.
-
Quantum computers are so far held back by their complexity. Engineers at Stanford have now demonstrated a new relatively simple design for a quantum computer where a single atom is entangled with a series of photons to process and store information.
-
Engineers at Stanford have created a new optical device that can easily manipulate light into basically any color desired. The system uses a series of modulators to fine-tune the frequencies of individual photons to change their color.
-
Engineers have developed a simple way to make colloidal diamonds that self-assemble. These structures have traditionally been tricky to manufacture in bulk, but with this new method they could be used to help make better photonic devices.
-
A new record has been achieved for the fastest internet speed from a single light source – an absolutely astounding 44.2 terabits per second, 44,000 times faster than the highest speed connection. It was made possible by a new kind of optical chip.
-
MIT spin off company Ayar Labs is combining electrons and light in new optoelectronic chips to speed up data transmission and reduce energy consumption in chip-to-chip communications by 95 percent.
-
There are plenty of strange phenomena in the universe, and fast radio bursts are among the more mysterious. So far, we don't know the source of these high-energy light bursts, but Harvard researchers propose they're caused by planet-sized alien transmitters for powering interstellar spacecraft.
-
SciencePhysicists have created a new set of energy-carrying particles dubbed "topological plexcitons" that show promise in greatly enhancing energy flows for solar cells and nanoscale photonic circuitry.
-
An international team of researchers has found a way to create microscopically-small lasers directly from silicon, unlocking the possibilities of direct integration of photonics on silicon, and a significant step towards light-based computers.
-
A team of physicists at TUM are working on nanowire lasers that are a thousand times thinner than a human hair and may one day lead to economical, high-performance photonic circuits.
