"Light Slowed to Enhance Microchips, Chinese Scientists Report"

Chinese scientists from the Shenzhen Institute of Advanced Technology have developed a method to slow down light on a microchip by over 10,000 times, improving the performance of photonic chips used in light sensing, communications, and computing. By reducing energy loss and utilizing materials with low absorption, the team was able to manipulate the speed of light, enhancing the interaction distance for light and potentially reducing manufacturing costs for photonic chips.

Navigating the Skies: Photonic Chips Revolutionize Drone Navigation in GPS Dead Zones

Researchers at the University of Rochester are developing photonic chips that could replace gyroscopes in drones, allowing them to navigate in areas where GPS signals are jammed or unavailable. By utilizing a quantum technique called weak value amplification, the scientists aim to achieve the same sensitivity level as bulk optical gyroscopes on small, handheld photonic chips. This advancement could revolutionize drone navigation as drones become smaller and more ubiquitous. The project, funded by the National Science Foundation, aims to implement weak value amplification on a tiny photonic chip with a high-quality factor ring resonator.

The Integration of Light-Powered Quantum Chips for Scalable AI.

The growing compute power required to train sophisticated AI models is causing a strain on mainstream chip technologies, leading to a shortage of server hardware and driving up prices. One proposed solution is photonic chips, which use light to send signals and could lead to higher training performance. However, while the technology generated excitement and investment a few years ago, investors and analysts now believe that photonic chips for AI are not the panacea they were once believed to be.
