JAKE SALTZMAN, NEWS EDITOR [email protected]A research team at Georgia Tech has demonstrated that large-area organic photodiodes, produced from solutions at low temperatures, can detect several hundred thousand photons every second. The process, the researchers said, is conceptually similar to the magnitude of light reaching a human’s eye from a single star. The low-noise and highly flexible organic devices allowed the researchers to substitute arbitrarily shaped, large-area photodiodes for the type of complex arrays that silicon photodiodes — which are more conventional — necessitate. Those arrays are expensive to...Read full articleRelated content from Photonics MediaArticlesUV-based 3D Printing Accelerates Multipurpose Glass ProductionCurrent 3D-printing techniques for fabricating glass involve time-consuming processes that require high temperatures and considerable resources to complete.
