Since 2000 he has been with the Group of Holography and Optical Processing, Universidad de Alicante (UA). He is Professor of Applied Physics in the Department of Physics, Systems Engineering, and Signal Theory (FISTS), where he has been Head of the Department. He is currently the Director of the Research Institute of Physics Applied to Sciences and Technologies at the UA. His research focuses on holographic recording materials and holographic memories, spatial light modulators based on liquid crystal, optical image processing, and diffractive optics. He has published more than 180 articles, and has more than 220 communications in congresses (16 invited). He is co-author of four book chapters, co-editor of five SPIE Proceedings Volumes, and co-inventor of one patent. He is senior member of OSA and Fellow of SPIE. A´ngel Lizana completed his MSc degree in Physics and PhD in Physics at the Autonomous University of Barcelona (Spain) in 2006 and 2011, respectively. His research interests include liquid crystal displays and their application to diffractive optics, as well as the design and implementation of polarimeters, and their application to biophotonics. He was a postdoctoral scientist in the PICM laboratory of the E´cole Polytechnique (France) in 2011–12 and in 2013–2014, where he has worked on the optimization and implementation of a polarimeter working in the infrared spectrum and on the analysis of polarimetric information for its application to the characterization of samples. Dr. Lizana has been an Associate Professor at the Autonomous University of Barcelona (UAB) since 2016. He is member of the SPIE and of Sociedad Espa ˜nola de O´ptica (SEDOPTICA). He was appointed General Secretary of SEDOPTICA in 2019. vii applied sciences Editorial Special Issue on Liquid Crystal on Silicon Devices: Modeling and Advanced Spatial Light Modulation Applications AndrésMárquez1,2,*andÁngelLizana3,* 1 InstitutoUniversitariodeFísicaAplicadaalasCienciasylasTecnologías(IUFACyT), UniversidaddeAlicante,03690Alicante,Spain 2 DepartamentodeFísica,IngenieríadeSistemasyTeoríadelaSeñal,UniversidaddeAlicante,Ap.99, 03080Alicante,Spain 3 DepartamentodeFísica,UniversitatAutònomadeBarcelona,08193Bellaterra,Spain * Correspondence:[email protected](A.M.);[email protected](Á.L.)

AmongthedifferentLC-basedtechnologies,liquidcrystalonsilicon(LCoS)hasbecomeoneofthe mostwidespreadtechnologiesforspatiallightmodulationinopticsandphotonics’applications[3–6].

LCoStechnologiesareusedasdisplaysaswellaspolarization,amplitude,andphase-onlyspatial lightmodulators, wheretheyachievefullphasemodulation. Duetotheirexcellentmodulating properties and high degree of flexibility, they are found in all sorts of spatial light modulation applications, suchasinLCoS-baseddisplaysystemsforaugmentedandvirtualreality, head-up display,head-mounteddisplay,projector,trueholographicdisplays,digitalholography,opticalstorage, adaptive optics, diffractive optical elements, super-resolution optical systems, optical metrology techniques,reconfigurableinterconnects,beam-steeringdevices,wavelengthselectiveswitchesin opticaltelecommunications,wave-frontsensingofstructuredlightbeams,holographicopticaltraps, orquantumopticalcomputing.
