  • Electrically tunable laser with cholesteric liquid crystal heliconical structure
    Patent number: 11444427
    Abstract: A lasing device includes an active layer comprising a cholesteric liquid crystal material and a laser dye, and a liquid crystal cell including spaced apart substrates defining a cell gap in which the active layer is disposed. The substrates include electrodes arranged to bias the active layer into an oblique helicoidal (ChOH) state. At least one substrate of the liquid crystal cell is optically transparent for a lasing wavelength range of the device.
    Type: Grant
    Filed: November 15, 2016
    Date of Patent: September 13, 2022
    Assignees: Kent State University, The University Court of the University of Aberdeen

  • Field induced and controlled heliconical structure of cholesteric liquid crystal
    Patent number: 9732277
    Abstract: A liquid crystal cell includes substrates defining a gap and electrodes having one of (i) an in-plane geometry generating an electric field parallel with the substrates and (ii) a top-down geometry generating an electric field across the gap between the two spaced apart substrates. A liquid crystal material disposed in the gap between the substrates comprises a chiral nematic material formed by a mixture of: 1-(4-cyanobiphenyl-4?-yl)-6-(4-cyanobiphenyl-4?-yloxy)hexane (CB6OCB) or ?,?-bis(4,4-cyanobiphenyl)nonane (CB9CB) dimeric liquid crystal material; at least one additional dimeric liquid crystal material; and a chiral dopant.
