Making smartphones smarter with see-through sensors

Your smartphone's display glass could soon be more than just a pretty face, thanks to new technology developed by researchers from Montreal and the New York-based company Corning Incorporated. The team has created the first laser-written light-guiding systems that are efficient enough to be developed for commercial use. They describe their work in a paper published today in The Optical Society's (OSA) open-access journal, Optics Express.
