How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...
Conceptual depictions of wavenumber-selective nonlinear wavelength conversion in Kerr photonic crystal microresonators. Spatial modulation of the microresonator inner sidewall (pictured center) with a ...
Scientists in Switzerland have developed an ultra-thin metalens that converts invisible infrared light into visible light by halving its wavelength, using nanoscale patterns stamped into a special ...
A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.230005 overviews how GaN-based LED achieves high rate Wavelength division multiplexing visible light communication system with ...
WASHINGTON — Researchers have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...
When it comes to appearances, the universe is a tricky place. Visible light occupies merely a sliver of the electromagnetic (EM) spectrum. To study the cosmos in its entirety, scientists must peer ...
Humanity’s most complex ground-based astronomy observatory, the Atacama Large Millimeter/submillimeter Array (ALMA), has officially opened for astronomers. The first released image, from a telescope ...
The world is awash with the color purple — lavender flowers, amethyst gemstones, plums, eggplants and purple emperor butterflies. But if you look closely at the visible-light portion of the ...
On a flyby of Venus, NASA’s Parker Solar Probe captured the first visible light images of the cloudy planet’s surface from space, a new study reports. The nightside view of the extremely hot surface ...
