Tunable supercontinuum light vector vortex beam generator using a q-plate

Opt Lett. 2013 Dec 1;38(23):5083-6. doi: 10.1364/OL.38.005083.

Abstract

Spatially coherent multicolored optical vector vortex beams were created using a tunable liquid crystal q-plate and a supercontinuum light source. The feasibility of the q-plate as a tunable spectral filter (switch) was demonstrated, and the polarization topology of the resulting vector vortex beam was mapped. Potential applications include multiplexing for broadband high-speed optical communication, ultradense data networking, and super-resolution microscopy.
