To overcome the lack of wavelength-selective extraction in existing on-chip metasurfaces, Chinese scientists developed a novel approach by leveraging a nonlocal on-chip design based on symmetry-broken ...

Orbital angular momentum (OAM) presents a promising degree of freedom for enhancing data transmission in optical communications. By utilising the helical phase front of light beams, OAM offers a ...

Concept of the robust NMR for MDM and its application in high-capacity optical fiber communication. The metasurface is trained by a neural network that can resist fiber mode fluctuations such as ...
