A zero-index waveguide

A zero-index waveguide 10/12/2017 02:02 PM EDT In 2015, Harvard University researchers developed the first on-chip metamaterial with a refractive index of zero, meaning that the phase of light could be stretched infinitely long. The metamaterial represented a new method to manipulate light and was an important step forward for integrated photonic circuits. Now, Harvard University researchers have developed a zero-index waveguide compatible with current silicon photonic technologies.
