New On-Chip Frequency Comb is 100x More Efficient

On-chip laser frequency combs — lasers that emit multiple frequencies or colors of light simultaneously separated like the tooth on a comb — are a promising technology for a range of applications including environmental monitoring, optical computing, astronomy, and metrology. However, these are still limited by one serious problem — they are not always efficient. ...

Does Your Computer Need More RAM? A Guide to Capacity

Having enough RAM is important for your laptop’s fast performance and responsiveness. RAM (Random Access Memory) is your computer’s temporary storage. And when you open many applications or several browser tabs, your RAM stores data that you need to retrieve quickly.  You probably know that more intensive laptop applications need more RAM. But does your ...

Researchers Kick-Start Spin Waves at Nanoscale in Pursuit of Low Energy Computing

An international team from Delft, Lancaster, Nijmegen, Kyiv, and Salerno has demonstrated a new technique to generate spin waves that propagate through the material at a speed much faster than the speed of sound. These so-called spin waves produce a lot less heat than conventional electric currents, making them promising candidates for future computation devices ...

Big Tech Companies Are Saying Goodbye to China

Big U.S. tech companies like Microsoft, Dell, and HP are reportedly looking to transfer a good chunk of their manufacturing out of China due to the sour trade relationship between Beijing and Washington. Moving out production “Hardware production has long been centered on China where production costs are cheaper, components of the tech supply chain ...
