Ultraviolet light has always sat at the edge of human perception, powerful yet invisible, more associated with sterilizing ...

Scientists have revealed a futuristic 'communication with light' system that uses light pulses instead of radio waves to ...

Researchers have developed a versatile organic crystal that can receive and transmit encrypted data from any angle, paving ...

Materials get their optical properties based on how much they reflect, absorb or transmit different wavelengths (colors) of light. Usually optical coatings either reflect or transmit a given color of ...

Despite the modern world relying heavily on digital optical communication, there has not been a significant improvement in the minimum attenuation—a measure of the loss of optical power per kilometer ...

Visible Light Communications (VLC), or Li-Fi, is a new optical wireless communications technology that promises spectacular amounts of new bandwidth for data transmissions. It uses visible light ...

The speed record for data transmission using a single light source and optical chip has been shattered. Engineers have transmitted data at a blistering rate of 1.84 petabits per second (Pbit/s), ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...

Neurons, the cells in brains and spinal cords that make up the central nervous system, communicate by firing electrical pulses. But scientists have found hints that neurons may transmit light as well, ...

A colorful display of plastic optical fibers Commercial optical fibers generally carry light that’s invisible to the eye. The colorful ones shown here transmit visible light, demonstrating how fiber ...
