Transmit beamforming is a versatile technique for signal transmission from an array of antennas to one or multiple users . In… Expand Quickly updatable hologram images using photorefractive (PR) polymer composite based on poly(N-vinyl carbazole) (PVCz) is… Expand Message passing algorithms have proved surprisingly successful in solving hard constraint satisfaction problems on sparse random… Expand In silica glass fibers, thermally excited acoustic phonons scatter light into the beam propagating in the forward direction. At… Expand In this talk we will present a new zonal wavefront sensor. The device consists of a multiplexed hologram which can reconstruct… Expand We demonstrate experimentally the existence of single-component multihump spatial solitons in a dye-doped nematic liquid-crystal… Expand We present and characterize theoretically and experimentally a photorefractive velocimeter. This device, based on two-wave mixing… Expand Research into and the development of data storage devices is a race to keep up with the continuing demand for more capacity, more… Expand A modification of the optical technique of impulsive stimulated thermal scattering that allows real‐time data acquisition is… Expand Albert Einstein has in his memoires written that he as a young boy pondered about what a light wave would look like to an… Expand
