After heating an optical fiber for nearly an hour, researchers completely changed its dispersion within a small section and ended up with a supercontinuum that covers a wide range...

Complete internal thermal state and full-aperture wavefront errors of a large optic can be accurately reconstructed using front-surface thermal imaging.

A three-layer photonic device combines phase-change materials with hydrogels to enable reversible, full-color image multiplexing for high-density optical storage devices via ambient...

The error self-compensation effect generated by monochromatic optical monitoring of coatings enables high accuracy to be achieved—even with significant thickness errors.

A device created by an international team of researchers converts a near-infrared (NIR) image into visible green light that can be captured via conventional or smartphone cameras...

When researchers in Germany froze liquid-core optical fibers to see what would happen, they discovered a larger-than-expected in-fiber Brillouin gain.

In a breakthrough, researchers in France and Germany demonstrate a photonic time crystal—with optical properties that change over time—and it has the potential to dramatically...

NASA selected Exail’s flight-proven lithium-niobate phase modulators for its Laser Interferometer Space Antenna (LISA) space mission, which highlights how industrialized electro...

Study shows no more than a total of 100,000 faint satellites—below naked eye visibility—can orbit Earth without damaging our ability to observe the night sky with modern telescopes...
