Publication number: 20070019173Abstract: A photolithography arrangement including an illumination source, which emits radiation with a predetermined wavelength directed towards a substrate, a projection mask for modulating the radiation of the illumination source, an optical system for imaging the radiation modulated by the projection mask onto the substrate, and a metal mask, which includes a transparent mask carrier and a metal mask arranged thereon, arranged successively in the beam path. The metal mask is designed so that the modulated radiation is transmitted through the metal mask by means of surface plasmons.Type: ApplicationFiled: January 12, 2006Publication date: January 25, 2007Applicant: Infineon Technologies AGInventor: Reinhard Marz

Patent number: 7058095Abstract: A resonator structure containing an active layer is subdivided into at least two sections in which mode spacings differ from one another by 7 to 10 percent on account of different length dimensions or as a result of grating structures provided therefor. Photonic crystals are integrated as longitudinal and, if appropriate, as lateral boundaries of the resonator structure. Variation of the currents in the sections enables the laser to be tuned in a wide wavelength range.Type: GrantFiled: November 25, 2003Date of Patent: June 6, 2006Assignee: Infineon Technologies AGInventors: Sven Mahnkopf, Reinhard März

Patent number: 6847750Abstract: The invention relates to a thermo-optical waveguide switch which is located on a substrate. Said switch comprises a glass layer, through which a waveguide extends. A hollow chamber which lies beneath the waveguide thermally decouples the latter from the substrate. At least two supports are located in the hollow chamber to provide mechanical stability. One production method for obtaining a thermo-optical waveguide switch consists of creating a glass layer with an arrangement of perforations on a substrate. At least one hollow chamber containing at least two supports is formed by isotropically underetching the glass layer. The hollow chamber is subsequently sealed and a waveguide is formed above said hollow chamber. Another production method first creates a waveguide in a glass layer which is formed on a substrate.Type: GrantFiled: November 22, 2000Date of Patent: January 25, 2005Assignee: Optun (BVI) Ltd.Inventors: Ingo Baumann, Reinhard Marz, Hartmut Schneider

Patent number: 6377592Abstract: In the method and the arrangement, a ratio (p2/P3)—which is independent of the total optical power of the laser (1)—between a power (p2) essentially containing only the wavelength (&lgr;) to be stabilized, which power is filtered out from a portion (P2) of the total power (P0), and an additional portion (P3) is measured and compared to a desired value (S0), and, given a deviation from the desired value (S0), the temperature of the laser (1) is controlled to the desired value (S0).Type: GrantFiled: September 27, 1999Date of Patent: April 23, 2002Assignee: Siemens AktiengesellschaftInventors: Franz Auracher, Reinhard März

Patent number: 4747649Abstract: A monolithically integrated WDM demultiplex module has a film wave guide of InGaAsP fashioned on a substrate, a photodiode of InGaAs being applied to the film wave guide. The photodiode is optically coupled to the film wave guide by a leakage coupling. A wavelength selection element in the form of a grating is provided in the surface of the film wave guide. The module can be manufactured with a single epitaxial step. Structures for increasing the crosstalk attenuation of the module and for a better coupling-in of radiation into the module are provided.Type: GrantFiled: December 27, 1985Date of Patent: May 31, 1988Assignee: Siemens AktiengesellschaftInventors: Jochen Heinen, Hans F.
