- 5/26/2017 Electro-optic switch sweeps refractive index by 60%
Researchers from North Carolina State University have discovered a technique for controlling red light with electric fields, with possible applications in photonics. It involves layers of thin material whose refractive index changes by up to 60%. “Unfortunately, it is very difficult to tune refractive index with electric fields,” said researcher Linyou Cao. “Previous techniques could ...

- 5/26/2017 Red green and blue from a single pixel
Researchers at the University of Central Florida have developed a colour changing surface tunable through voltage. “We can make a red sub-pixel go to blue, for instance,” said researcher Debashis Chanda. “In other displays that is not possible because they need three static colour filters to show the full RGB colour. We don’t need that ...
