Generation of arbitrary full Poincar\'e beams on the hybrid-order Poincar\'e sphere
Abstract
We propose that the full Poincar\'e beam with any polarization geometries can be pictorially described by the hybrid-order Poincar\'e sphere whose eigenstates are defined as a fundamental-mode Gaussian beam and a Laguerre-Gauss beam. A robust and efficient Sagnac interferometer is established to generate any desired full Poincar\'e beam on the hybrid-order Poincar\'e sphere, via modulating the incident state of polarization. Our research may provide an alternative way for describing the full Poincar\'e beam and an effective method to manipulate the polarization of light.
