New paper in Optics Letters about the production of non-diffracting vector beams


Vector beamsWe published a new paper in Optics Letters, entitled Nondiffracting vector beams where the charge and the polarization state vary with propagation distance. The paper appeared published in the OL issue of May 2016.

In this work we  generate nondiffracting vector beams where the charge and the polarization state vary with the propagation distance. We use reflective geometry where a parallel-aligned spatial light modulator is used to spatially modulate two orthogonal linear polarizations. We encode spiral phases with equal charge but with opposite signs onto the two polarization directions to encode a vector beam and add two axicon phases. Both the charge and the phase shift between the two axicons can be varied along the focus line.

This work has been done in collaboration with our friends at San Diego State University, and was designed during the recent visit of Ignacio Moreno to SDSU in February 2016.
