A novel quantum effect observed in a carbon nanotube film could lead to the development of near-infrared lasers and other optoelectronic devices, according to scientists....

Researchers have developed a flat optical component that is simultaneously a metalens, a microscope objective that can resolve details smaller than a wavelength of light, and an optical vortex and...

Recent years have seen an explosion of research in flat optical components fashioned with so-called metasurfaces – intricately engineered, planar configurations of subwavelength elements. But most of these flat optical...

Lasers that emit ultrashort pulses of light are critical components of technologies, including communications and industrial processing, and have been central to fundamental Nobel Prize-winning research in physics. Although first...

"The size of the market for optics in medical imaging dwarfs that for MRI, computed tomography, or ultrasound," says Cameron Piron of Synaptive Medical. "Optical techniques are not always considered...
