recommendations! Published in 2020 at "Optics Communications"

DOI: 10.1016/j.optcom.2019.125028

Abstract: Abstract There is significant interest in the generation of complex vector beams, where the combined polarisation and phase profile is chosen to have particular properties. These beams have often been implemented in an adaptable manner… read more here.

DOI: 10.1080/09500340.2016.1277563

Abstract: Abstract A compact common-path interferometry is proposed to measure the wavefront aberration generated from liquid crystal spatial light modulator (LC-SLM). The LC-SLM is encoded with an aberration pattern and illuminated with a linearly polarized light… read more here.

DOI: 10.1109/lpt.2025.3583264

Abstract: Beam shaping and uniformity are critical requirements in various optical applications, including laser processing, aesthetic treatments, medical therapies, holography, and optical communication. The Gerchberg-Saxton (GS) algorithm and the hybrid input-output (HIO) algorithm are widely used… read more here.

DOI: 10.1364/oe.483736

Abstract: We describe multiple optical functionalities obtained with a simple electrically tunable liquid crystal element that can be controlled by 4 electrodes, which are connected to a serpentine shaped transparent indium tin oxide layer. We experimentally… read more here.
