The invisible light spectrum, encompassing ultraviolet and infrared wavelengths, has long beguiled the human eye. A revolutionary lens technology is now making this unseen light accessible, heralding ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...

Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could ...

Kerala University has secured a patent for an innovation in a light-emitting material that is capable of producing the full visible spectrum of colours from a single host material.
