Tunable optical vortex arrays from a single nematic topological defect.

Etienne Brasselet1.   

Abstract

We report on the generation of tunable structured light fields endowed with various sets of phase singularities from a single topological defect in a nematic liquid crystal mesophase. The experimental demonstration relies on the use of electric field-induced nonsingular topological defects called "umbilics."
