Cylindrical Vector Beams

Cylindrical Vector Beams


Cylindrical vector beams (CVB) are solutions of the solutions of the vector wave equation that obey cylindrical symmetry both in amplitude and polarization. We proposed a method to efficiently produce light beams with radial, azimuthal, and hybrid polarization, through a few-mode fiber excited by a Laguerre–Gaussian beam. With different input polarization we can selectively excite different combinations of modes from the LP11 group. We showed how to transform the output beam into a cylindrical vector beam in free-space through various polarization transformations.
