[17p-C104-2] A soft route to high-resolution liquid crystal vortex masks : developments and perspectives

Etienne Brasselet1,2 (1.Bordeaux Univ., 2.CNRS)

Keywords:optical vortices, liquid crystals, optical imaging

We will discuss how the self-organization of soft matter into topological defects can be harnessed to establish a novel route to create wavelength-tunable high-resolution liquid crystal vortex masks without need of artificial spatial patterning techniques. Recent progresses and examples of applications of this self-engineered approach will be presented.
