WARSAW: Researchers have created a nanoscale structure that traps infrared light in a layer just 40 nanometres thick--over 1,000 times thinner than a human hair. By using a unique material with ...

Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase singularities. While they have been widely studied in recent decades, two ...

Scientists were surprised to discover cassowaries glow under ultraviolet light. It may help the birds distinguish between different species. The casque of a southern cassowary glows blue-green in ...

THE investigations on the molecular scattering of light now in progress under the writer's direction (regarding which previous communications have been published in NATURE) have brought to light some ...

Transformation optics is a technique that simplifies the modelling of optical devices by altering the coordinate system, warping space to control the trajectories of light rays. The mathematical tool ...
