Recently, Harvard scientists in the United States for the first time designed a metamaterial with zero refractive index that can be integrated into a chip, in which light can reach "infinity." This result opens the door to exploring zero-index physics and its use in integrated optics. This zero-index material consists of a gold-plated silicon pillar array embedded in a polymer matrix with no phase advancement that produces a quiescent phase whose wavelength can be considered infinite. It sounds like a violation of the law of relativity, but it is not. Nothing in the universe can run faster than light, but there is another speed of light, the speed of the crest motion, called the phase velocity, which depends on the material through which light travels. Such as light through the water, the phase velocity will be squeezed by the wavelength becomes smaller, into the water, the phase velocity will be greater, because the wavelength is stretched. In media, the refractive index to express the slowdown of the light wave peak, the higher the refractive index, the greater the interference of light diffraction, such as the refractive index of water is about 1.3. In zero-index materials, however, there is no phase advance of the wave trough, which means that the light behaves no longer like a moving wave, but rather a stationary phase, with all wave crests lining an infinite wavelength. Crests and troughs only serve as a temporal variable, not space. The light is hard to squeeze or manipulate, and this uniform phase makes the light stretchable, squeezed or twisted without losing energy. The incorporation of zero-index materials onto the chip promises a bright future, especially in the area of ​​quantum computing. According to a report by the Physicist's Organization Network, zero-index metamaterials are embedded in a polymer matrix by a gold-plated silicon pillar array that couples silicon waveguides with standard integrated photonic devices and chip interfaces to enable people to work in different die Manipulate light, squeeze, twist light, and even reduce the beam diameter to nanometers. Erik Mazur, professor at the School of Physics and Applied Physics at the School of Engineering and Applied Science (SEAS) at the University, said it is a good new way of controlling light. "This on-chip metamaterial opens the door to exploring zero-index physics and its use in integrated optics." Li Yang, a postdoctoral fellow at the Masur team, said in a typical silicon waveguide that weak and ineffective optical energy constraints are a major barrier to the integration of photonic circuits, Constraints in the structure of electromagnetic energy provides a solution.
