Patent number: 10073037Abstract: The invention relates to the use of a construct for the detection of an analyte using surface enhanced spectroscopic techniques. The construct includes linked surfaces, where the link is formed by a linker providing a fixed inter-surface separation between the linked surfaces, wherein the linker is a linking compound, and at least one of the surfaces is the surface of a nanoparticle. The linking compound is suitable for interacting with the analyte. The linking compound may be a cucurbituril. The surface enhanced spectroscopic technique may be surface enhanced Raman spectroscopy (SERS).Type: GrantFiled: June 24, 2011Date of Patent: September 11, 2018Inventors: Richard William Taylor, Jeremy John Baumberg, Sumeet Mahajan, Tung-Chun Lee, Oren Alexander Scherman, Setu Kasera, Roger Coulston

Patent number: 9561615Abstract: A polymer opal material comprises a three dimensionally periodic arrangement of core particles in a matrix material and exhibits structural color via Bragg reflection. IN a process for manufacturing such a material, a sandwich structure is provided, of a precursor composite material held between first and second sandwiching layers. A relative shear strain of at least 10% is imposed on the precursor composite material by curling the sandwich structure around a roller. The shear strain is cycled, in order to promote the formation of the three dimensional periodic arrangement.Type: GrantFiled: January 12, 2012Date of Patent: February 7, 2017Assignees: CAMBRIDGE ENTERPRISE LIMITED, FRAUNHOFER-GESELLSCHAFT ZUR FORDERGUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Jeremy John Baumberg, David Snoswell, Christopher Finlayson, Qibin Zhao, Gotz Peter Hellmann, Peter Wolfgang Andreas Spahn, Christian Gerhard Schafer

Publication number: 20150109657Abstract: A composite optical device has a layer of a composite optical material mounted on a substrate. The layer of composite optical material has substantially uniform thickness. The composite optical material is a polymer opal, in that it has a three dimensional arrangement of core particles distributed in a matrix, the refractive index of the material of the core particles being different to the refractive index of the material of the matrix and the three dimensional arrangement being capable of having a periodicity such that, when a surface of the material is illuminated with white light, the composite material exhibits structural colour. The local stiffness of the substrate is different at different positions of the substrate.Type: ApplicationFiled: November 30, 2012Publication date: April 23, 2015Inventors: Jeremy John Baumberg, David Robert Evan Snoswell, Andreas Kontogeorgos, Götz Peter Hellmann, Peter Wolfgang Andreas Spahn

Patent number: 8743452Abstract: Metal nanovoids are grown on a stretchable plastic film. The fabrication proceeds by assembling the template of a single layer of close packed silica spheres on a conducting substrate. A conducting layer is then electrochemically grown on top to form a master. An elastomeric precursor is then coated on the master (e.g. by spinning) and is cured before removal. The resulting plastic film is then coated with a thin (e.g. 20 nm) layer of noble metal (e.g. Au, Ag or Cu), to produce a flexible film. Applications for such tuneable structural color would be coating of injection molded artifacts, such as mobile phone covers, car bodies to form an iridescent skin, wall and fascia decorations, loudspeaker coatings, architectural tent coverings, and clothing.Type: GrantFiled: May 22, 2008Date of Patent: June 3, 2014Assignee: Cambridge Enterprise Limited of the Old SchoolsInventors: Jeremy John Baumberg, Phillip Nigel Bartlett, Sumeet Mahajan, Robin Cole

Patent number: 6856737Abstract: There is provided a non-linear optical device for enhancing the bandwidth accessible in the nonlinear generation of an optical signal. The device comprises a planar optical waveguide, the planar optical waveguide being operative to generate an optical output from an optical input having an input bandwidth by means of a non-linear optical process, the optical output having a wavelength within an accessible bandwidth, wherein the planar optical waveguide is operative to enhance the accessible bandwidth such that the ratio of the accessible bandwidth to the input bandwidth is at least 4. The device is particularly applicable to broad optical continuum generation, but may also be used in a parametric oscillator or amplifier arrangement with broad tuning range.Type: GrantFiled: August 27, 2003Date of Patent: February 15, 2005Assignee: Mesophotonics LimitedInventors: Greg Jason Parker, Jeremy John Baumberg, James Wilkinson, Martin David Brian Charlton, Majd Zoorob, Maria Caterina Netti, Nicolas Perney, John Lincoln

Patent number: 6483100Abstract: Silicon possesses an indirect band-gap, which limits its use in some photonic applications. A phonon generator is included in a silicon-based device, which promotes electron-hole recombination and so allows silicon to emit photons efficiently. Phonons may be generated by optical or electrical stimulation or as a result energy relaxation of hot-electrons.Type: GrantFiled: November 13, 2000Date of Patent: November 19, 2002Assignee: Hitachi, Ltd.Inventors: David Arfon Williams, Jeremy John Baumberg
