| 84 | PHOTONIC SENSING METHOD AND DEVICE | PCT/ES2010070502 | 2010-07-21 | WO2011012753A3 | 2011-07-28 | GARCIA RUPEREZ JAIME; MARTI SENDRA JAVIER; MARTINEZ ABIETAR ALEJANDRO JOSE |
| The invention relates to a method and a device for photonic sensing based on periodical dielectric photonic forbidden band structures in which the sensing process is carried out by the measurement of the variation of the amplitude of the signal at the output of the device. The amplitude variation is a result of a variation in the refractive index of the structure, as a consequence of the presence of the substances to be sensed. The invention is especially characterised by its simplicity in the sensing process performed by direct measurement of the output amplitude, without the need to carry out a frequency scanning, its high level of integration, which enables a smaller design, and its adaptability to dielectric structures having one, two and three dimensions. | ||||||
| 85 | FLUORESCENCE DETECTION ENHANCEMENT USING PHOTONIC CRYSTAL EXTRACTION | PCT/US2007024234 | 2007-11-19 | WO2008136812A3 | 2008-12-24 | CUNNINGHAM BRIAN T; GANESH NIKHIL; MATHIAS PATRICK C; BLOCK IAN D |
| Enhancement of fluorescence emission from fluorophores bound to a sample and present on the surface of two-dimensional photonic crystals is described. The enhancement of fluorescence is achieved by the combination of high intensity near-fields and strong coherent scattering effects, attributed to leaky photonic crystal eigenmodes (resonance modes). The photonic crystal simultaneously exhibits resonance modes which overlap both the absorption and emission wavelengths of the fluorophore. A significant enhancement in fluorescence intensity from the fluorophores on the photonic crystal surface is demonstrated. | ||||||
| 86 | METHOD FOR MANUFACTURING A SINGLE-CRYSTAL FILM, AND INTEGRATED OPTICAL DEVICE COMPRISING SUCH A SINGLE-CRYSTAL FILM | PCT/CH2008000065 | 2008-02-14 | WO2008098404A3 | 2008-12-11 | POBERAJ GORAZD; GUARINO ANDREA; GUENTER PETER |
| The invention relates to a method for manufacturing a single-crystal film, e.g. a metal oxide or organic crystal film, based on the known ion slicing technology. In a first step, ions are implanted into a donor crystal structure to form a damage layer within the crystal structure at an implantation depth below a top surface of the crystal structure, the top surface and said damage layer defining at least in part the single- crystal film to be detached from the crystal structure. Thereafter, the crystal structure is indirectly bonded to a substrate by a bonding layer between the crystal structure and the substrate, this bonding layer comprising a polymer adhesive. After curing the polymer, the laminate is exposed to a temperature increase to effect detachment of the single-crystal film from the crystal structure. The invention has the advantage of less stringent requirements for surface smoothness and flatness. Therefore, it enables a very reproducible fabrication of high-quality and large area thin films, e.g. of a metal oxide (e.g. ferroelectric) or organic crystal. | ||||||
| 87 | METHOD AND APPARATUS FOR MEASURING AND MONITORING DISTANCES, PHYSICAL PROPERTIES, AND PHASE CHANGES OF LIGHT REFLECTED FROM A SURFACE BASED ON A RING-RESONATOR | PCT/US2006012805 | 2006-04-06 | WO2006108096A3 | 2007-10-25 | VOLLMER FRANK; FISCHER PEER |
| A method and apparatus for performing refractive index, birefringence and optical activity measurements of a material such as a solid, liquid, gas or thin film is disclosed. The method and apparatus can also be used to measure the properties of a reflecting surface. The disclosed apparatus has an optical ring-resonator in the form of a fiber-loop resonator, or a race-track resonator, or any waveguide-ring or other structure with a closed optical path that constitutes a cavity. A sample is introduced into the optical path of the resonator such that the light in the resonator is transmitted through the sample and relative and/or absolute shifts of the resonance frequencies or changes of the characteristics of the transmission spectrum are observed. A change in the transfer characteristics of the resonant ring, such as a shift of the resonance frequency, is related to a sample's refractive index (refractive indices) and/or change thereof. In the case of birefringence measurements, rings that have modes with two (quasi)-orthogonal (linear or circular) polarization states are used to observe the relative shifts of the resonance frequencies. A reflecting surface may be introduced in a ring resonator. The reflecting surface can be raster-scanned for the purpose of height-profiling surface features. A surface plasmon resonance may be excited and phase changes of resonant light due to binding of analytes to the reflecting surface can be determined in the frequency domain. | ||||||

| 90 | METHOD OF FABRICATION TO SHARPEN CORNERS OF WAVEGUIDE Y-BRANCHES IN INTEGRATED OPTICAL COMPONENTS | PCT/US0202285 | 2002-01-25 | WO02077715A3 | 2003-05-22 | WANG XIAOLIN; LEON FRANCISCO |
| Substantially sharp corners for optical waveguides in integrated optical devices, photonic crystal devices, or for micro-devices, can be fabricated. Non-sharp corners such as rounded corners (28), are first formed using lithographic patterning and vertical etching, Next, isotropic etching is used to sharpen the rounded corners. A monitor can be used to determine if the rounded corners (28) have been sufficiently sharpened by the isotropic etching. | ||||||
| 91 | MODE CONTROL USING TRANSVERSAL BANDGAP STRUCTURE IN VCSELS | PCT/DK0200146 | 2002-03-07 | WO02073753A2 | 2002-09-19 | OESTERGAARD JOHN ERLAND; BIRKEDAL DAN |
| A vertical cavity surface emitting laser (VCSEL) having a photonic band gap (PBG) region formed within or adjacent to a first and/or a second mirror, or within a spacer layer positioned between a gain region and at least one of the mirrors. The PBG region has a predetermined periodicity which substantially prevents the generated light from propagating the region, and defines a light aperture without the periodicity so as to allow the generated light to propagate through the aperture. The PBG region does not extend through the gain region, thereby allowing the full gain region to be used. Controls the efficiency of laser action by suppressing or preventing laser action in certain modes without losses, rather the modes are made forbidden. Energy from the forbidden modes is eventually coupled back to the allowed mode(s). Provides a separation of the confinement of the gain region and the mode control without introducing energy losses. | ||||||
