scientists designed zero refractive index metamaterials to let the speed of light on a chip 'infinite'
recently, Harvard University scientists devised a refractive index is zero for the first time, can be integrated on a chip of metamaterials, the speed of light in which can achieve 'infinity'. This outcome to explore zero refractive index of physics and its application in integrated optics opened the door.
this zero refractive index material composed of gold-plated silicon column array embedded polymer array, will produce a stationary phase, propulsion and its wavelength can be regarded as infinite.
it seems that this violated the laws of relativity, but actually not. Nothing in the universe can run faster than light, but there is another light speed, the speed of the wave movement, known as phase velocity, the speed of light speed depends on the light through the material. The velocity of light passing through the surface, for example, can be extruded and smaller because of wavelength, after entering the water, phase velocity will be bigger, because the wavelength is drawn. In the medium, the refractive index to represent the light wave speed slow down, the higher the refractive index, the greater the interference of light wave diffraction, the refractive index of water is 1. 3.
in the zero refractive index materials, no phase advance of peaks and troughs, which means that the light no longer behave like a sport, but a stationary phase, all the peaks and troughs in the infinite long wavelength. Peaks and troughs only as a kind of time variable, rather than space.
it is hard to be squeezed light or manipulation, and this kind of uniform phase can make light stretching, squeezing, or distorted without loss of energy. The zero refractive index materials incorporated into the chip, is expected to bring bright application prospects, particularly in the field of quantum computation.
according to physicists organization network, gold-plated zero refractive index metamaterials by silicon column array embedded in the polymer matrix, can with standard silicon waveguide integrated photonic devices, chip interface coupling together, let people can manipulate light between different chips, extrusion, distorts the light, even the beam diameter down to nanoscale. John paulson, the school of engineering and applied sciences ( 海) Physics and applied physics professor Eric Eric mazur says, this is a great new way to control the light. 'This kind of chip metamaterials, to explore zero refractive index of physics and its application in integrated optics opened the door. '
the first author theses and postdoctoral researcher Eric mazur team '( Transliteration) Said, in general silicon waveguide, weak and ineffective energy constraints, is an obstacle that integrated photonic circuits, the zero refractive index material for electromagnetic energy constraints in different waveguide structure provides a solution.
