Reconfigurable beams with arbitrary polarization and shape distributions at a given plane

Abstract: Methods for generating beams with arbitrary polarization based on the use of liquid crystal displays have recently attracted interest from a wide range of sources. In this paper we present a technique for generating beams with arbitrary polarization and shape distributions at a given plane using a Mach-Zehnder setup. The transverse components of the incident beam are processed independently by means of spatial light modulators placed in each path of the interferometer. The modulators display computer generated… Show more

“…the SOP is identical for all points at any transverse plane along the beam propagation. However, there exist light beams possessing non-homogenous polarization, known as vector beams, such as the well known radial or azimuthal polarizations [101] or even beams with more involving polarization distributions [124][125][126]. The non-homogeneous polarization distribution of vector beams can lead to singular points where the SOP is exactly circular (C points), lines along which the SOP is linear (L lines) or disclinations where the instantaneous electric field is null [127][128][129][130].…”

“…Figure 3 depicts an experimental setup based on a Mach-Zehnder interferometer able to generate arbitrary spatially-variant polarized focused beams. An extended explanation on how this system is used to generate beams with arbitrary polarization and shape can be found in [17]. An unpolarized quasi monochromatic input beam is split into two beams by means of polarizing beam splitter PBS 1 .…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] In this context, an important issue is to develop the theoretical framework to determine the behavior of a polarizer on a focused beam. [15][16][17] We have recently published a study on how linear polarizers modify a tightly focused field.…”
