TORONTO, ON, June 19, 2009 – Light sensors that act like pixels in a digital camera have been created by scientists at the University of Toronto. The sensors benefit from a phenomenon known as multi-exciton generation (MEG). Until now, no group had collected an electrical current from a device that takes advantage of MEG. According to the group, this discovery could lead to advancements in the performance of a variety of electronic devices, including digital cameras. The paper appears in the June 19 edition of the journal Science. Researchers created a light sensor – like a pixel in a digital camera – that...Read full article

    digital camera
    A camera that converts a collected image into pixels that are black or white digital or shades of gray. The digital data may then be manipulated to enhance or otherwise modify the resulting viewed image.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
