Patent number: 12010790Abstract: A high-frequency circuit including a circuit board which bears at least one electronic component and a conductor structure, and including a waveguide structure manufactured separately from the circuit board. The waveguide structure is positioned on the circuit board in such a way that high-frequency signals are transferable between the conductor structure on the circuit board and the waveguide structure. The waveguide structure is held with the aid of press-fit pins on the circuit board.Type: GrantFiled: October 18, 2021Date of Patent: June 11, 2024Assignee: ROBERT BOSCH GMBHInventors: Christian Hollaender, Klaus Baur, Gustav Klett, Klaus Voigtlaender, Michael Schoor, Ronny Ludwig

Publication number: 20220390668Abstract: A system for producing an optical fiber with inscribed grating array is described. The system comprises a fiber drawing apparatus for drawing an optical fiber, a writing system for inscribing a grating in the optical fiber during the drawing process of the optical fiber and a controller for controlling the driving of the writing system. According to the present invention the fiber drawing apparatus also comprises a fiber length and/or drawing detecting means for determining the fiber length and/or fiber drawing speed and/or a fiber drawing parameter during the drawing process. The controller thereby is configured for capturing information from the fiber length and/or drawing detecting means and for controlling the writing system based on the captured information captured from the fiber length and/or drawing detecting means.Type: ApplicationFiled: August 16, 2022Publication date: December 8, 2022Inventors: Eric LINDNER, Johan VLEKKEN, Christian VOIGTLÄNDER, Bram VAN HOE, Manfred ROTHHARDT, Hartmut BARTELT

Patent number: 9360617Abstract: The invention relates to a mode filter for reducing higher-order modes, with an optical fiber (1), which has a core (2) and a cladding (3) surrounding the latter, wherein the cladding (3) and core (2) have refractive indices that differ from one another. In order to develop an alternative to the prior art, the mode filter according to the invention is designed in such a manner that the fiber (1) has, in a transition region (4) between core (2) and cladding (3), at least one local refractive index modification region (5) which is arranged in the radially outer region of the core (2) and extends into the region of the cladding (3).Type: GrantFiled: September 27, 2012Date of Patent: June 7, 2016Assignees: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.

Patent number: 8891917Abstract: The invention relates to a transverse mode filter in an optical waveguide (3). The aim of the invention is to produce a transverse mode filter that permits a monolithic construction of a laser in a multi-mode waveguide. To achieve this, according to the invention the filter comprises a Fabry-Perot cavity integrated into the optical waveguide (3) and comprising two reflective elements (5) situated at a distance from one another. In addition, the waveguide (3) is modified in the region of the Fabry-Perot cavity and/or in the region of the reflective elements (5) in relation to the remaining regions of the waveguide with respect to the effective refractive index of at least one mode of the waveguide.Type: GrantFiled: September 15, 2010Date of Patent: November 18, 2014Assignees: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V., Friedrich-Schiller-Universitaet JenaInventors: Jens Ulrich Thomas, Christian Voigtlaender, Stefan Nolte, César Jáuregui Misas, Fabian Stutzki, Jens Limpert, Andreas Tuennermann
