The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

a. Schematic of a CBR sample on six-legged piezoelectric substrate mounted on a chip carrier. Dimensions are not to scale. b. Optical microscopy image of a finished sample. A tilted scanning electron ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...
