The structures that UpNano produces in the 3D printer are so small that they are recognisable neither with the naked eye nor with a strong optical microscope. Only under a scanning electron microscope ...
CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At ...
Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...
Very-long baseline interferometry (VLBI) is a technique in radio astronomy whereby multiple radio telescopes cooperate to bundle their received data and in effect create a much larger singular radio ...
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 ...
