The future of optical communications just got brighter. In a development reported in Advanced Photonics, researchers from Nanjing University have introduced iso-propagation vortices (IPVs), a novel ...

Optical waves propagating through air or multi-mode fiber can be patterned or decomposed using orthogonal spatial modes, with far-ranging applications in imaging, communication, and directed energy.

Throughout the last decade, optical fiber has gained more and more popularity as a transmission medium. The unprecedented capacity of the fiber makes it an ideal medium for transport of digital video ...
