Physicists control the polarization of the light, lowering its speed up to 10 times

So-called spatial light modulators that serve as a base for all LCDs, among other things, can be arranged so that each pixel can switch the light quickly, making it brighter or weaker by rotating the polarization of light. According to Tatyana Dolgova, senior researcher of the Laboratory of Nanophotonics and Metamaterials, Faculty of Physics, MSU, these fast, new spatial light modulators can be used when creating holographic memory, three-dimensional displays, as well as the accurate refractive index sensors and magnetic field sensors.
