The low-light photographic performance of smartphones could soon get a significant boost, thanks to the development of a new type of color filter. Created by an engineer at the University of Utah, the new filter is said to let in three times more light than conventional filters, resulting in brighter and sharper images with better color reproduction.
Silicon photonics is an emerging technology that incorporates electronic circuits using photons of laser light rather than electrons to transmit, receive, and manipulate information. As such, a silicon photonic CPU could potentially process information at the speed of light – millions of times faster than computers available today. In a step towards this goal, engineers working at the University of Utah have developed an ultra-compact photonic beam-splitter so small that millions of these devices could fit on a single silicon chip.
