In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending ...

Offers new possibilities to control light across the spectrum and insight into light–matter interactions. The device, reported in Advanced Photonics, functions as an optical black hole or optical ...

Each colour within the visible light spectrum has its own narrow band of wavelength and frequency. When white light passes through a coloured filter, all colours are absorbed except for the colour ...

A team of researchers has engineered a groundbreaking optical device that mimics the physics of black holes and their ...

Examples include super-lenses to view objects at the molecular scale; invisibility cloaks, which refract all visible light; and perfect wave absorption for energy harvesting or noise reduction.
