Photonics at Yale brings together researchers from Physics, Engineering, Biology and other departments who are working on the latest generation of lasers and nanostructures, expanding the possibilities for imaging and communication devices of all kinds, as well as for developing more efficient solar panel cells. Yale researchers have significantly advanced novel and complex laser systems, and have developed a new class of “random lasers” which could improve the processing time and clarity of pictures from medical imaging equipment.  Yale scientists also built the world’s first anti-laser, in which incoming beams of light cancel each other out, a technology that holds promise for optical computing and radiology. And working across departments, researchers at Yale are uncovering how biological nanostructures create brilliant colors in birds and recreating the effect with lasers.
