Recent advances in 40-Gbit/second optical and electronic technologies suggest that service providers may soon be able to harvest those technologies to lower costs and to speed provisioning. Crucial to ...

Chromatic dispersion management is one of the most important technologies for high-bit-rate DWDM systems. In particular, the transmission quality in 40Gbit/second systems is highly sensitive to ...

A research team recently demonstrated active manipulation of chromatic dispersion, achieving achromatic focusing within a designated broadband. The development of metasurfaces opened a horizon for the ...

The research group led by Professor Yijun Feng and Professor Ke Chen from Nanjing University reports a hybrid-phase strategy ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

Broadband achromatic wavefront control, a cornerstone of next-generation photonic systems that supports full-color imaging, multi-spectral sensing ...
