Refractive index - the ratio of the speed of electromagnetic radiation in a medium to its speed in a vacuum - can be modulated fast enough to generate photonic time crystals (PTCs) in the near-visible ...

At 4 degrees Kelvin, most electro-optic materials falter. Nanoelectronics R&D center imec has now successfully engineered ...

PTCs, materials in which refractive index rises and falls rapidly in time, are the temporal equivalent of photonic crystals in which the refractive index oscillates periodically in space causing, for ...

With optical sensors, XR devices, and IT OLED projected to be among the fastest-growing consumer and industrial technology markets in the coming years, the combination of the new PixMicro with the ...
