a zero-index waveguide stretches a wave of light infinitely long

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.
