CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

CU Boulder researchers have designed microscopic “racetracks” that trap and amplify light with exceptional efficiency. By using smooth curves inspired by highway engineering, they reduced energy loss ...

An overwhelming majority of handheld devices these days have ambient light sensors built into them. A large percentage of TVs and monitors do, too, and that proportion is growing. The sensors allow ...
