    • Large-aperture switchable thin diffractive lens with interleaved electrode patterns 

      Li, Guoqiang; Valley, Pouria; Giridhar, M. S.; Mathine, David L.; Meredith, Gerald; Haddock, Joshua N.; Kippelen, Bernard; Peyghambarian, Nasser (Georgia Institute of TechnologyAmerican Institute of Physics, 2006-10)
      The authors report on a high-performance large-aperture switchable diffractive lens using nematic liquid crystal that can be used as an adaptive eyewear. The odd- and even-numbered ring electrodes are separated in two ...

    • Photorefractive polymer composite operating at the optical communication wavelength of 1550 nm 

      Tay, Savaş; Thomas, Jayan; Eralp, Muhsin; Li, Guoqiang; Kippelen, Bernard; Marder, Seth R.; Meredith, Gerald; Schülzgen, Axel; Peyghambarian, Nasser (Georgia Institute of TechnologyAmerican Institute of Physics, 2004-11)
      A photorefractive polymer composite sensitized at 1550 nm through direct two-photon absorption has been developed. We show an external diffraction efficiency of 3% in four-wave-mixing experiments and perform holographic ...
