Cloaking devices and metamaterials are hot topics in the realm of science where optics blurs into materials science. By crafting materials that can interact with specific wavelengths of light, ...

Portland, Ore. — All natural materials bend electromagnetic radiation–from microwaves to visible light–in the same predictable direction: away from a line perpendicular to their surface, or away from ...

Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That's why high-power microscopes are so big and telephoto lenses so long.

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 visible-wavelength ...

Our little-known ability to see infrared light could occur when pairs of photons combine their energies to appear as one "visible" photon Although we do not have X-ray vision like Superman, we have ...

Researchers have demonstrated the first planar lens that works with high efficiency within the visible spectrum of light -- covering the whole range of colors from red to blue. The lens can resolve ...
