The speed of light varies in materials, impacting fiber optics, laser systems, and semiconductor lithography through complex electromagnetic interactions.

Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, ...

A project from the Harvard SEAS lab of metamaterials developer Federico Capasso could help address the issue of unwanted light dispersion in optical systems. This could be a particular benefit for ...

A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...

Optomechanical microcavities are extremely small structures with diameters of less than 10 micrometers (about a tenth of a human hair) inside which light and mechanical vibrations are confined. Thanks ...
