Realization of a Four-Electrode Liquid Crystal Device With Full In-Plane Director Rotation

Abstract: Abstract-A liquid crystal device with micrometer-scale hexagonal electrodes has been fabricated and characterized. By using weak anchoring at the liquid crystal interfaces, the orientation of the director is completely governed by the applied electric fields. The appropriate voltage waveforms applied to electrodes allow the director in the liquid crystal layer to be rotated in the plane parallel to the substrates over large angles, exceeding 180• . This paper is a technological and experimental verification of… Show more

“…Maximal tuning will be achieved with very weak adhesion of the molecules to the surface. This is, in practice, hard to achieve as the anchoring energy always has a finite value [8] and the molecules experience some anchoring forces even when no alignment layer is present. The anchoring strength of the rubbed nylon-6 surface is very high.…”

“…Aunque el dispositivo comparte similitudes con las celdas planares, sus aplicaciones se encuentran más bien en el terreno de la propagación frontal de luz, para modicar la polarización de un haz, por ejemplo. El funcionamiento experimental del dispositivo se publicó en [128]. En el año 2011 se publica un dispositivo basado en celda planar con una conguración de electrodos nada trivial, de forma alternante en las variables transversales, y que consigue ángulos de giro de los nematicones tan grandes como 70 o [129].…”
