A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously developed at Skoltech can operate at a speed of 240 GHz ...

(Nanowerk News) A new graphene-based optical logic gate uses collective oscillations of electrons to process light waves in a far smaller space than existing designs. The device also benefits from low ...

In a collaboration between scientists from Physics and Chemistry at the University of Bayreuth and Physical Chemistry at the University of Melbourne, it has now been possible to realize optically ...

Photonic crystal systems offer a versatile platform for implementing optical logic gates by exploiting the periodic modulation of refractive index to control light propagation at subwavelength scales.

Optical logic operations and computing systems harness photons rather than electrons to perform arithmetic and logic functions, offering prospects for unprecedented processing speed, bandwidth and ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...
