Power/Performance Bits: June 30


Up-converting lasers Researchers at the University of Pennsylvania developed a filter chip that can convert the output from low-cost lasers to have the same frequency noise as big, expensive lasers, making them suitable for applications such as LiDAR. The noise in a laser's frequency is an important indicator of quality. Low-quality, noisy lasers have more random variations, making them use... » read more

Power/Performance Bits: May 23


Biosupercapacitor Researchers from UCLA and the University of Connecticut designed a biological supercapacitor, a new biofriendly energy storage system which operates using ions from fluids in the human body. The device is harmless to the body's biological systems, say the researchers, and could lead to longer-lasting cardiac pacemakers and other implantable medical devices. The supercapa... » read more
