Manipulation of full Poincaré beams on a hybrid Poincaré sphere

We present a hybrid Poincaré sphere, whose eigenstates are defined as a pair of circularly polarized fundamental-mode Gaussian beam and a Laguerre-Gaussian beam, to describe the so-called full Poincaré beam. We also show that any desired full Poincaré beam over the hybrid Poincaré sphere via modulating the incident polarization state of light and two cascaded half-wave plates. This research provides an alternative way for charactering and manipulating the full Poincaré beam and an effective method to control the polarization state of light.
