Abstract

In this paper, a high efficiency method to generate vector beam based on a single liquid crystal spatial light modulator (LCSLM) is proposed. In this method, the system used to generate vector beam adopts a collinear configuration which makes the system more stable and the core components of the system include a half-wave plate, a reflective phase-only LCSLM and a quarter-wave plate. With the proposed system, the polarization states distribution of output beam could be modulated by controlling the phase pattern displayed on LCSLM and the relative intensity of the two orthogonal components in the beam reflected by LCSLM. We conducted a theoretical analysis of the method and demonstrated the validity and feasibility of the method experimentally. The experiment results are highly consistent with the results obtained through theoretical simulations.
