Publication number: 20160282809Abstract: The improvement of the performance of holographic glasses with recorded holograms as measured by a figure of merit of the holographic glasses is disclosed. The improvement in the figure of merit of the holographic glasses is obtained at least in part with the addition of arsenic in the formation of the holographic glasses. The presence of arsenic increases the figure of merit as measured at a wavelength of interest of a holographic glass with a recorded hologram as compared to a holographic glass with a recorded hologram that does not contain arsenic.Type: ApplicationFiled: June 13, 2016Publication date: September 29, 2016Applicant: PD-LD, Inc.Inventors: Eliezer M.

Publication number: 20120019884Abstract: Three-dimensional holographic elements are disclosed. Three-dimensional Bragg gratings recorded on bulks of optical material are included in the disclosure. Such elements may be manufactured by placing a three-dimensional bulk of optical material directly behind a recorded master hologram, directing a reference beam onto a master hologram such that a replica of the master hologram is recorded in the optical material. The replica may form the three-dimensional holographic element. The master hologram may be Bragg grating formed on a surface of a transparent substrate.Type: ApplicationFiled: May 23, 2011Publication date: January 26, 2012Applicant: PD-LD, INC.Inventors: Boris L.

Patent number: 7528385Abstract: Apparatus and methods for controlling the spectral shape of a Bragg grating element (“VBG”) filter are disclosed. An optical system can be adapted to deliver a recording beam to the front focal plane of a lens. The recording beam may cause to be formed, in the front focal plane of the lens, an optical distribution that represents the desired filter response of the VBG element. A recording medium sample may be placed in the back focal plane of the same lens. The lens creates a true Fourier transform of the distribution in the optical plane directly on the recording medium. Via coherent interference with the plane reference wave, both the amplitude and the phase of the Fourier transform are transferred to the amplitude and phase envelope of the VBG imprinted on the recording material. A mask representing the desired filter shape may be placed in the front focal plane of the lens.Type: GrantFiled: April 3, 2006Date of Patent: May 5, 2009Assignee: PD-LD, Inc.Inventors: Boris L.

Patent number: 5744267Abstract: A photorefractive (PR) device comprises of a layer of a novel photorefractive polymer composite sandwiched inbetween two transparent electrodes. The PR polymer composite comprises a photoconducting polymer, a photosensitizer, a novel second-order, non-linear optical chromophore, and a plasticizer in an amount sufficient to provide the PR polymer composite with a glass transition temperature below about 45.degree. C. The PR polymer composite is capable of internally storing image patterns generated by interfering two coherent light beams inside the material. The PR polymer composite shows high diffraction efficiencies (near 100%) and high net two-coupling gain (>200 cm.sup.-1). The writing of information is reversible. Consequently, the device is suitable for read/write holographic storage and real-time image processing applications, and is capable of being poled at essentially room temperature.Type: GrantFiled: September 10, 1996Date of Patent: April 28, 1998Assignee: Arizona Board of Regents acting for and on behalf of University of ArizonaInventors: Klaus Meerholz, Bernard Kippelen, Nasser N.
