Generation and control of photorefractive soliton lattices

2003 European Quantum Electronics Conference. EQEC 2003 (IEEE Cat No.03TH8665), 2003

This study extends the experimental creation of arrays of parallel propagating solitons as first demonstrated previously to larger lattices and investigates potential control and waveguiding features. The dependence of mutual interaction on the separation of adjacent channels is studied in order to show the potential of these solitonic lattices for applications in telecommunications.

  • Generation and control of photorefractive soliton lattices

    This study extends the experimental creation of arrays of parallel propagating solitons as first demonstrated previously to larger lattices and investigates potential control and waveguiding features. The dependence of mutual interaction on the separation of adjacent channels is studied in order to show the potential of these solitonic lattices for applications in telecommunications. This work also demonstrates waveguiding using red (/spl lambda/ = 633 nm) and infrared light ( /spl lambda/ = 1.55 /spl mu/m). In the latter case, a spatially resolved infrared-to-visible light converter using a gas discharge system is used. Moreover, this study shows induced control of solitons in these large lattices using coherent and incoherent steering beams.

  • LuI/sub 3/:Ce-a new scintillator for gamma ray spectroscopy

    In this paper, we report on a new cerium doped, high atomic number scintillator, LuI/sub 3/:Ce, for gamma ray spectroscopy. Crystals of this material have been grown using Bridgman process. LuI/sub 3/ crystals doped with 0.5 and 5% Ce/sup 3+/ show high light output (/spl sim/50 000 photons/MeV) and fast principal decay constant (23 to 31 ns). The Ce/sup 3+/ emission peaks at 474 nm. Energy resolution of LuI/sub 3/:Ce coupled to photomultiplier tube (PMT) and measured at 662 keV was /spl sim/11% [full- width at half-maximum (FWHM)]. Timing resolution of LuI/sub 3/-PMT and BaF/sub 2/-PMT detectors operating in coincidence mode was measured to be 210 ps (FWHM). Potential applications of this scintillator are discussed.

Films deposition was performed by immersion of the substrates into coating solution and flow-coating process. Investigation of the surface chemistry and morphology of the wood substrates before and after deposition were obtained by means of atomic force microscopy and optical microscopy.

  • Properties of the high-density scintillator cerium fluoride

    A new radiation-hard scintillator, CeF/sub 3/, has been found. It has a density of 6.16 g/cm/sup 3/ and a radiation length of 1.7 cm. Two scintillation decay constants have been detected with time constants of approximately 2 ns and 31 ns, peaking at 310 nm and 340 nm, respectively. The amount of scintillation light from the present samples is about 50% that of BGO (bismuth germanate). It is concluded that CeF/sub 3/ fills a niche in PET (position emission tomography) in that it has the potential of providing a less expensive high-rate camera. It has a better stopping power for 511-keV photons with BaF/sub 2/, while its scintillation is detectable with a glass photomultiplier.<<ETX>>

  • New Cerium Activated Scintillating Glasses

    The synthesis of cerium activated scintillating glasses is being continued, and two new types have been developed. One of these, a magnesium aluminum borate, is similar to the alkali borate glasses reported previously and was made in an effort to provide a scintillating glass with the highest possible boron content in which a reasonable pulse height could be retained. Its pulse height with gamma excitation is 5.0 per cent of a Nal(Tl) crystal. The second glass developed is a lithium magnesium aluminum silicate. This glass has a pulse height 14.0 per cent of the Nal(Tl) crystal and is the most efficient material prepared in this program. Preliminary studies indicate that energy transfer between the base glass and the activator does occur, and that the efficiency of glass scintillators is not limited by the absence of energy transfer. mission.

  • Magneto-optical properties of Y/sub 3-x-y/Ce/sub x/La/sub y/Fe/sub 5/O/sub 12/

    Yttrium iron garnet YIG has been characterized extensively for its use in magneto-optic devices, such as optical isolators and magnetic field sensors. The effects of doping cerium and lanthanum into the YIG host are reported. In optical isolator applications operating at 1.31 /spl mu/m and 1.54 /spl mu/m, where miniaturization and temperature stability are important, cerium and lanthanum-containing compositions are considered as alternatives to pure YIG. Measurements were made of the Faraday rotation as a function of temperature, extinction ratio, and saturation magnetization in several garnet compositions. Improvement of optical transmission at 1.31 /spl mu/m and 1.54 /spl mu/m was achieved by the incorporation of small amounts of calcium.

  • Nitrogen Oxide Decomposition on Cerium Modified ZSM-5 Zeolite in the Presence of Oxygen

    In this study ZSM-5-type zeolite was synthesized by sol-gel and Cu-(Ce)-ZSM-5 catalysts were prepared by ion-exchange. The prepared catalysts were characterized by XRD, TPD, ICP-AES, FTIR and tested in the removal of NO in the presence of oxygen. The results showed that oxygen had obviously negative impact on activity of catalysts due most Cu+were oxided to Cu2+with increasing of temperature. The introduction of Ce can improve the resistance of catalysts to oxygen in some degree. Modified catalysts exhibited the highest activity at about 623 K and then decreased with temperature increased. The amount of Ce retained in the zeolite might has impact on activity of prepared catalysts.

  • Synthesis and growth mechanism of NaFe/sub 4/P/sub 12/ nanowires

    Filled skutterudite NaFe/sub 4/P/sub 12/ single crystal nanowires were synthesized by using a hydrothermal-reduction-alloying method. X-ray diffraction (XRD), Electron diffraction (ED), Raman scattering, as well as elemental analysis were used to characterize the product. High-resolution transmission electron microscope (HRTEM) was used to investigate the microstructure of the nanowire. A growth mechanism of NaFe/sub 4/P/sub 12/ nanowire was proposed.

  • Tunable ultraviolet microchip Ce/sup 3+/:LiLuF laser

    Ultraviolet microchip cerium fluoride lasers have been demonstrated with high efficiency (up to 50%) and ultra-low threshold (/spl sim/1.4 /spl mu/J). These lasers represent simple compact wavelength converters to 306-331 nm for microchip Nd:YVO/sub 4/ laser.

  • A new scintillating glass for high energy physics applications

    A scintillating glass has been developed containing cerium (3+) oxide in an aluminate host glass. In this material the scintillation emission spectrum is red-shifted relative to that observed for Ce/sup 3+/ in silicate glasses. Emission and absorption spectra are more widely separated in the aluminate composition, suggesting that which glasses might have improved light- transmission properties. The refractive index is high, making it a potentially interesting material for use in fiber-optic tracking detectors.<<ETX>>
