A project from the Harvard SEAS lab of metamaterials developer Federico Capasso could help address the issue of unwanted light dispersion in optical systems. This could be a particular benefit for ...

The relentless demand for higher bandwidth and lower latency in global telecommunications continues to drive innovation in fibre optic systems. Dispersion, the phenomenon where different wavelengths ...

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a problem that’s limited imaging and display technologies for years. By ...

The achromatic lens can focus the incident RCP and LCP light onto two distinct positions without chromatic aberration over a wide bandwidth. Broadband achromatic wavefront control, a cornerstone of ...

BARRINGTON, N.J., Aug. 12, 2021 /PRNewswire/ — Edmund Optics(R), leading global manufacturer and supplier of optical components, now internally manufactures short pulse optics with low group delay ...

Despite of impressive successes already achieved on metasurfaces, most fascinating light-manipulation effects were only demonstrated under normal-incidence excitations. The angular dispersions of the ...

Unlike existing photodetectors that construct and integrate wavelength- and/or polarization-sensitive elements in space or time to improve the detection ability (range and sensitivity), this ...

A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many colors. The trick combines two geometric phase effects so each spin channel ...

A new study published in Nature, conducted by an international collaboration team led by Prof. Wei Li from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy ...
