Researchers demonstrate a platform for future optical transistors

Illustration of experimental structures. Photo credits: Department of Physics, ITMO University Leading research groups in the field of nanophotonics work on the development of optical transistors – key components for future optical computers. These devices process information using photons instead of electrons, reducing heat and increasing operating speed. However, photons do not interact well with each other, which is a …

A tiny optical cavity could enable quantum networks

A nanophotonic cavity created by the Faraon laboratory. Photo credit: Faraon Lab / Caltech Caltech engineers have shown that atoms in optical cavities – tiny boxes for light – can form the basis for creating a quantum internet. Her work was published on March 30th by the magazine nature. Quantum networks would connect quantum computers via a system that does …

Researchers are developing rewritable optical components for 2-D lightwaves

A 2D prism. Picture credits: Harvard SEAS In 1884, a schoolmaster and theologian named Edwin Abbott wrote a novella called Flatland, which tells the story of a world populated by sentient two-dimensional forms. While conceived as a satire of rigid Victorian social norms, Flatland has long fascinated mathematicians and physicists, serving as the setting for many thought experiments. Such a …

Bird or hare: An optical illusion of an animal confuses the Internet

No, it's definitely a bird. But hey, you are the judge. A video of a black beast scraping nicely spreads quickly on the Internet as people take sides in another big debate. Daniel Quintana, a scientist at Oslo University in Norway, is responsible for all of this – he found the video on a sharing site on Sunday and tweeted …

Self-organizing materials can form patterns that may be useful for optical devices

Scanning electron micrographs of the crystal structure of the block copolymer material illustrating its unusual quasicrystal symmetries. Regions with different symmetry properties are highlighted in different colors, and examples of the different patterns that resemble some old tile patterns are shown in the attached diagrams.

Alien life BREAKTHROUGH: Alien hunters make PETABYTE of radio and optical data public | Science | News

Looking for alien life shows no signs of letting up as it continues to be pursued today by national space agencies, academics and charities. However, no one has convincingly proven the existence of any biological beyond the bounds of our planet. Breakthrough Listen is a £ 80million ($ 100million) alien-hunting project launched by dignitaries including scientific colossus Professor Stephen Hawking. …

Poor Astronomy | A young, hot exoplanet that was first observed with optical interferometry

Exoplanet discoveries seem to occur virtually every day; We become really good at discovering alien worlds orbiting strange stars. At present, about 4,000 such discovered planets are counted, which is unbelievable since the first one was not found until 1992! There are many different ways to discover them, but one of the most impressive is direct imaging: a picture of …
