Record-breaking chip can transmit entire internet’s traffic per second

Posted on by

A new photonic chip design has achieved a world record data transmission speed of 1.84 petabits per second

The speed record for data transmission using a single light source and optical chip has been shattered once again. Engineers have transmitted data at a blistering rate of 1.84 petabits per second (Pbit/s), almost twice the global internet traffic per second.

High harmonic lasers unlock a resolution boost for optical microscopy

Posted on by

Physicists at the Australian National University say that optical microscopes should get a huge boost in magnification, after their discovery of a new high harmonic laser illumination technique, using a tiny cylinder 1/50th the width of a human hair.Co… Continue reading High harmonic lasers unlock a resolution boost for optical microscopy→

Nanopillared lenses let scientists trap individual atoms with light

Posted on by

“Optical tweezers” – systems that focus light to trap and manipulate individual atoms – could pave the way for powerful quantum devices, but they can be a little cumbersome. Researchers have now developed a simplified, smaller design for optical tweeze… Continue reading Nanopillared lenses let scientists trap individual atoms with light→

We’ve all heard of the smoke test, and we know that it’s the lowest possible bar for performance of an electronic device. If it doesn’t burst into flames when power …read more Continue reading Homebrew Optical Sensor Helps Your Diesel Pass the Smoke Test→

Amazing optical microphone can separate multiple instruments from afar

Posted on by

Researchers at Carnegie Mellon University have presented some remarkable audio from a new optical microphone system that uses cameras to see and reconstruct sonic vibrations. Remarkably, it can cleanly separate a single instrument playing in a group.Co… Continue reading Amazing optical microphone can separate multiple instruments from afar→

Modular optical computer chip allows stackable swappable functions

Posted on by

Engineers at MIT have developed a modular computer chip with components that can communicate using flashes of light. This could allow for electronics that can easily be upgraded with new sensors or processors, rather than replacing the whole chip.Conti… Continue reading Modular optical computer chip allows stackable swappable functions→

Researchers at the University of Pennsylvania have developed a powerful new optical chip that can process almost 2 billion images per second. The device is made up of a neural network that processes information as light without needing components that … Continue reading Optical brain-like chip processes almost 2 billion images per second→

“Expanding hole” illusion tricks the brain into dilating the pupils

Posted on by

When you view the image above, does it look like black smear in the center is expanding? If it does, that means you’re like most people – and your brain may even think that you’re entering a tunnel, adjusting your eyes accordingly.Continue ReadingCateg… Continue reading “Expanding hole” illusion tricks the brain into dilating the pupils→

Record-breaking camera keeps everything between 3 cm and 1.7 km in focus

Posted on by

In photography, depth of field refers to how much of a three-dimensional space the camera can focus on at once. A shallow depth of field, for example, would keep the subject sharp but blur out much of the foreground and background. Now, researchers at … Continue reading Record-breaking camera keeps everything between 3 cm and 1.7 km in focus→
