Synthesis of full Poincare beams by means of uniaxial crystals Piquero Sanz, Gemma María Monroy, L. Santarsiero, Massimo Alonzo, M. González de Sande, Juan Carlos © 2018 IOP Publishing Ltd. This work has been partially supported by Spanish Ministerio de Economía y Competitividad under project FIS2016-75147. A simple optical system is proposed to generate full-Poincare beams (FPBs), i.e. beams presenting all possible states of (total) polarization across their transverse section. The method consists in focusing a uniformly polarized laser beam onto a uniaxial crystal having its optic axis parallel to the propagation axis of the impinging beam. A simple approximated model is used to obtain the analytical expression of the beam polarization at the output of the crystal. The output beam is then proved to be a FPB. By changing the polarization state of the input field, full-Poincare beams are still obtained, but presenting different distributions of the polarization state across the beam section. Experimental results are reported, showing an excellent agreement with the theoretical predictions. 2023-06-17T12:28:04Z 2023-06-17T12:28:04Z 2018-06 journal article 2040-8978 10.1088/2040-8986/aabdad https://hdl.handle.net/20.500.14352/12166 http://dx.doi.org/10.1088/2040-8986/aabdad http://iopscience.iop.org eng FIS2016-75147 open access IOP Publishing, Ltd.
