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 ...

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, ...

As measuring translucent materials has endless applications, focus is given to the generic principle of transmission measurement. Measurements of foils, thin film, glass and even liquids in cuvettes ...

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 ...

Physicists in the US have created the first nanoscale coaxial cables for the transmission of light. Operating much like the coaxial cables used to distribute television and radio signals, the cables ...

Plant growth is heavily dependent on light, but it’s not just leaves and shoots that make use of the Sun’s rays, according to a new study in Science Signaling, and reported by New Scientist. Using a ...

Researchers at the University of California, Los Angeles (UCLA) have unveiled a new optical technology that enables precise focusing of light—only in one direction. This novel unidirectional focusing ...

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 ...

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 ...

A recent review published in the journal Buildings has spotlighted optical fiber light-transmitting concrete (LTC), a ...
