Cylindrical vector beam (CVB) multiplexing has emerged as a powerful technique to boost signal channels. Coupling and separating CVBs are two pivotal elements in CVB multiplexing communication.

Typically, light emitted from standard lasers has a controllable degree of freedom (DoF) which may be polarisation or beam shape. By suitably manipulating a laser with the introduction of specialised ...

A research team led by Associate Prof. Wang Anting from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a method for multidimensional ...

Propagate light through any kind of medium -- be it free space or biological tissue -- and light will scatter. Robustness to scattering is a common requirement for communications and for imaging ...

The ability to structure a laser pulse in various inventive ways has been key to several breakthroughs in spectroscopy. Control of a laser pulse's polarization has been a particularly useful factor in ...

Researchers have found a way to use the full beam of a laser light, to control and manipulate minute objects such as single cells in a human body, tiny particles in small volume chemistry, or working ...
