The self-organized helix structure with the axis lying in the plane of the cavity acts as a one-dimensional periodic photonic lattice. This is possible due to the unique properties of liquid crystals, which are elongated molecules that resemble a pencil,\u201d explains Prof. Jacek Szczytko from the Faculty of Physics at the University of Warsaw, where research on novel optical microcavities is being conducted.<\/p>\n<p>A cholesteric structure is a <a href=\"https:\/\/phys.org\/tags\/spiral+structure\/\" rel=\"tag\" class=\"\">spiral structure<\/a> made up of layers of almost parallel oriented molecules lying in a single plane. From layer to layer, the orientation of the molecules is gently twisted, which altogether builds up a helical structure reminiscent of DNA helixes or \u2018piggyback\u2019 noodles. The direction perpendicular to the layers of molecules determines the axis of the helix formed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities.
