Spatial multiplexing for robust optical vortex transmission with optical nonlinearity

Weiru Fan,
Tianrun Chen,
Xiaobin Tang
et al.

Abstract: Optical vortex beams, with phase singularity characterized by a topological charge (TC), introduces a new dimension for optical communication, quantum information, and optical light manipulation. However, the evaluation of TCs after beam propagation remains a substantial challenge, impeding practical applications. Here, we introduce vortices in lateral arrays (VOILA), a novel spatial multiplexing approach that enables simultaneous transmission of a lateral array of multiple vortices. Leveraging advanced learni… Show more

“…Various singular phenomena have been explored, including exceptional points, bound states in the continuum (BICs), and optical vortices. In particular, BICs, which lie within the radiation continuum in momentum space but are completely decoupled from the free space, exhibit infinitely high Q factors.…”
