As data rates in optical networks increase, designers need to pay increasing attention to peculiarities in the fiber-optic medium.One of the most important of these peculiarities is dispersion, ...

The research group led by Professor Yijun Feng and Professor Ke Chen from Nanjing University reports a hybrid-phase strategy that unlocks broadband achromatic wavefront control for both circular ...

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 ...

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 ...

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 ...

Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, ...

The speed of light varies in materials, impacting fiber optics, laser systems, and semiconductor lithography through complex ...

New research has shown how the quantum mechanical principle of strong coupling opens unrivalled possibilities for designing optical filters. A team of researchers from the University of Cologne, ...
