An optical fiber about the thickness of a human hair can now carry the equivalent of more than 10 million fast home internet connections running at full capacity.

A team of Japanese, Australian, Dutch, and Italian researchers has set a new speed record for an industry standard optical fiber, achieving 1.7 Petabits over a 67km length of fiber. The fiber, which contains 19 cores that can each carry a signal, meets the global standards for fiber size, ensuring that it can be adopted without massive infrastructure change. And it uses less digital processing, greatly reducing the power required per bit transmitted.

Macquarie University researchers supported the invention by developing a 3D laser-printed glass chip that allows low loss acce...

This diagram shows the setup for an imaging method that mapped electrical signals using a sheet of graphene and an infrared laser. The laser was fired through a prism (lower left) onto a sheet of graphene. An electrode was used to send tiny electrical signals into a liquid solution (in cylinder atop the graphene), and a camera (lower right) was used to capture images mapping out these electrical signals.

Team creates a system to visualize faint electric fields. Scientists have enlisted the exotic properties of graphene, a one-atom-thick layer of carbon, to function like the film of an incredibly sensitive camera system in visually mapping tiny electric fields in a liquid...

By harnessing the photoswitchable Rabi splitting, all-optical light modulators and rewritable waveguides were developed. The demonstration of Rabi splitting in the HPWMs (hybrid plasmon–waveguide modes)  will further advance scientific research and device applications of hybrid plasmon–molecule systems.

A military drone flying on a reconnaissance mission is captured behind enemy lines, setting into motion a team of engineers who need to remotely delete sensitive information carried on the drone’s chips. Because the chips are optical and not electronic, the engineers can now simply flash a beam of UV light onto the chip to instantly erase all content. Disaster averted...
