Patent number: 6552864Abstract: A method and a system for generating a beam of radiation in a target plane located in a near-filed region of a radiation emitting means. A beam of radiation having a substantially plane wavefront is emitted. A normal Bessel beam, having its transverse profile substantially in the form of a Bessel function, is produced from said emitted beam of radiation. The normal Bessel beam is produced in a first medium of a refraction index n1 and is directed towards the target plane located in a second medium having a refraction index n2, such that n2<n1. Passage of the normal Bessel beam from the first medium into the second medium results in the generation of an evanescent Bessel beam of radiation propagating in the second medium. The evanescent Bessel beam has a center lobe significantly smaller in size than the wavelength of radiation in the second medium, and basically retains its shape in the second medium.Type: GrantFiled: February 25, 2000Date of Patent: April 22, 2003Assignee: Ramot at Tel Aviv University Ltd.Inventor: Shlomo Ruschin

Publication number: 20020136517Abstract: A waveguide for guiding electromagnetic radiation of a given range of wavelengths includes a transparent substrate made from non-polymer material, preferably glass, into which at least one elongated channel is etched. A polymer material with a higher refractive index than that of the substrate is deposited within, and extends along, the channel, so as to define a waveguide. The regions of the substrate adjacent to the ends of the channel are preferably treated, such as by ion-exchange, to form secondary waveguide portions, optically coupled to the polymer waveguide, for input and output optical coupling with the waveguide. Also disclosed is a production method for such waveguides.Type: ApplicationFiled: February 20, 2001Publication date: September 26, 2002Applicant: Ramot University Authority for Applied Research and Industrial Development Ltd.Inventors: Shlomo Ruschin, Tali Hurvits

Patent number: 6432278Abstract: A method for controlling an index of refraction of silica glass, and in particular quartz glass, is disclosed. The method for controlling the index of refraction of silica glass includes the use of a vacuum ultraviolet laser beam having the same or shorter wavelength absorbable by the silica glass. The vacuum ultraviolet laser beam is irradiated to the silica glass to cause photodissociation of a Si—O bond at the point of irradiation. An index of refraction may also be altered using a vacuum ultraviolet laser beam having a longer wavelength absorbable by the silica glass.Type: GrantFiled: January 22, 2001Date of Patent: August 13, 2002Assignee: The Institute of Physical and Chemical ResearchInventors: Koji Sugioka, Shlomo Ruschin, Jie Zhang, Satoshi Wada, Hideo Tashiro, Koichi Toyoda
