A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

A team from UNamur, Harvard, MTU and Sparrow Quantum has designed a photonic chip that dramatically extends the entanglement range between quantum emitters by leveraging a near-zero refractive index ...

Biological condensates are small, membraneless organelles typically consisting of multiple proteins and nucleic acids within ...

Researchers report the development of ultrahigh refractive index metamaterials which are integrated with a low refractive index polymer producing distributed Bragg reflector (DBR). The highest ...

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 ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) say they have made it easier to manipulate light at the nanoscale. They have developed the first on-chip ...
