Patent number: 8243574Abstract: The invention relates to the writing and optical reading of high-density information. The higher energy density at the center of the reading laser beam is used for modifying the energy structure of an active layer in such a way as to make it capable of bearing surface plasmons. The coupling of the laser beam and the active layer thus modified can then excite surface plasmons in an interface between a dielectric layer and the active layer. These surface plasmons are disturbed by physical marks having very small dimensions and written in the optical storage medium; these disturbances generate a remote-field optical response which can be detected by a detector. The operation is carried out in super-resolution, the surface plasmons being generated only at the center of the laser beam and not at the periphery. It is therefore possible to write and to read again marks having dimensions of size smaller than the theoretical resolution of the optical reading system.Type: GrantFiled: April 30, 2008Date of Patent: August 14, 2012Assignee: Commissariat a l'Energie AtomiqueInventors: Salim Mimouni, Fabien Laulagnet

Patent number: 7606132Abstract: Disclosed are a cantilever-type near-field probe capable of easily improving an optical throughput and being applied to a head of an optical data storage and a method of manufacturing the same. An oxide film is formed on a silicon substrate having dielectric films formed as a mask layer on upper and lower portions thereof, and a circular dielectric film formed on the upper mask layer and providing a function of a holder. A distal end of the probe has a parabolic structure by use of an effect of a bird's peak provided due to a difference of growth rate of the oxide film produced by the dielectric film, thereby forming the initial probe. After the dielectric film is removed from the initial probe, a bottom surface of the silicon substrate is removed, thereby providing the probe with the near-field aperture having a high throughput.Type: GrantFiled: October 12, 2005Date of Patent: October 20, 2009Assignee: Electronics and Telecommunications Research InstituteInventors: Kibong Song, Eunkyoung Kim, Sung Qyu Lee, Kang Ho Park, Jun Ho Kim

Patent number: 7598499Abstract: In a particle-beam projection processing apparatus a target (41) is irradiated by means of a beam (pb) of energetic electrically charged particles, using a projection system (103) to image a pattern presented in a pattern definition means (102) onto the target (41) held at position by means of a target stage; no elements—other than the target itself—obstruct the path of the beam after the optical elements of the projection system. In order to reduce contaminations from the target space into the projection system, a protective diaphragm (15) is provided between the projection system and the target stage, having a central aperture surrounding the path of the patterned beam, wherein at least the portions of the diaphragm defining the central aperture are located within a field-free space after the projection system (103).Type: GrantFiled: October 30, 2007Date of Patent: October 6, 2009Assignee: IMS Nanofabrications AGInventor: Elmar Platzgummer

Publication number: 20090116363Abstract: In an information memory apparatus having minute areas for storing information arranged in x, y and z directions three-dimensionally, parallel rays are irradiated to a memory area MA in a direction perpendicular to a z-axis to take projection images of the memory area MA while rotating the memory area MA around the z-axis little by little. The light rays irradiated at this time have a size which covers at least a direction of an x-y plane of the memory area. A computation unit PU finds data and addresses of minute areas distributed three-dimensionally by performing computation based upon the principle of computer tomography on the projection images. As for data writing, a change is given to optical transmissivity or light emission characteristics by irradiating laser light focused by a lens OL placed outside the memory area to a desired minute area and causing heat denaturation within the pertinent minute area.Type: ApplicationFiled: October 30, 2008Publication date: May 7, 2009Inventors: Takao WATANABE, Toshimichi Shintani, Takeshi Maeda, Akemi Hirotsune, Tomonori Sekiguchi
