A novel four-wave mixing technique that restructures parts of light pulses to travel faster than the speed of light could improve the timing of communications signals and help examine the propagation of quantum correlations. Einstein’s theory of relativity states that light passing within a vacuum represents the universal speed of light. A short burst of light emerges as a type of symmetric curve. The curve’s leading edge cannot surpass the speed of light, but the peak of the pulse can be altered forward and backward. Recent experiments demonstrated that, by increasing...Read full article

    four-wave mixing
    A phenomenon that occurs in WDM and DWDM systems when three closely spaced signal wavelengths near the zero-dispersion wavelength interact with each other, producing a fourth wavelength that interferes with the original signal. A moderate amount of dispersion can be designed into some systems to ensure that this effect does not take place.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
