Publication number: 20140127829Abstract: An optical device has a deformable solid substrate, and a two dimensional array of metal particles which is carried by the substrate. The array provides a controlled separation between nearest-neighbour particles. Deformation of the substrate produces corresponding variation in the controlled separation such that the two dimensional array undergoes a transition between metallic and insulator surface reflectance.Type: ApplicationFiled: May 16, 2012Publication date: May 8, 2014Applicant: Cambridge Enterprise LimitedInventors: Jeremy Baumberg, Fumin Huang, Matthew Millyard

Patent number: 7864313Abstract: A planar optical platform for generating a Raman signal from a foreign object comprises an input region and an output region, for receiving and extracting optical radiation, optically coupled to a plasmonic band structure region. The plasmonic band structure region comprises a layer of a first material, having a first refractive index, patterned with an array of sub-regions of a second material, having a second refractive index, wherein a side-wall of each sub-region is coated with a metallodielectric layer. The array of sub-regions gives rise to a plasmonic band structure and, in use, each sub-region confines a plasmon resonance excited by optical radiation coupled into the plasmonic band structure region, which gives rise to a Raman signal from a foreign object placed proximate the plasmonic band structure region. The platform may be incorporated into a spectroscopic measurement system and is particularly useful for surface-enhanced Raman spectroscopy of analyte molecules.Type: GrantFiled: January 26, 2009Date of Patent: January 4, 2011Assignee: Renishaw Diagnostics LimitedInventors: Jeremy Baumberg, Sven Mahnkopf, Majd Zoorob, John Lincoln, James Wilkinson

Publication number: 20050047702Abstract: 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. The planar waveguide geometry permits easy integration in more complex photonic integrated circuits such as a Michelson interferometer for low coherence interferometry based optical coherence tomography.Type: ApplicationFiled: August 27, 2004Publication date: March 3, 2005Inventors: Greg Parker, Jeremy Baumberg, James Wilkinson, Martin Charlton, Majd Zoorob, Maria Netti, Nicolas Perney, John Lincoln
