Now, researchers have developed a zero-index waveguide compatible with current silicon photonic technologies. In doing so, the team observed a physical phenomenon that is usually unobservable -- a ...

Improving the properties of the waveguide to carefully control polarization and other attributes allows the waveguides to be smaller, and alleviating crosstalk allows these smaller waveguides to ...

Artist's impression of a zero Index waveguide. In 2015, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) developed the first on-chip metamaterial with a ...

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...

Pasternack has released six new waveguide detectors that cover a broad frequency range of 26.5 GHz to 110 GHz. The devices are all zero-biased, so no external DC bias or mechanical tuning is required.
