August 5, 2017. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References Re34790 Connector for coupling optical fibers to an emitter or receiver of luminous energy Detachable connector for optical fibres Packaged fiber optic modules Detachable coupling for optical fibres LED having self-aligned lens Device for coupling a light source and an optical waveguide Opto-electronic module housing Method of manufacturing a terminal device for an optical fiber, and device thus obtained Method of making a light-emitting-diode (led) with spherical lens InventorAssigneeApplicationNo. 905938 filed on 08/05/1997US Classes:385/93, Including lens385/35SphericalExaminersPrimary: Ngo, Hung V.Attorney, Agent or FirmInternational ClassG02B 006/36AbstractAn improved connector is provided. The connector comprises: an optoelectronic transducer having a transducer axis through a center of the optoelectronic transducer, and a first alignment means integrated with the optoelectronic transducer; an optical fiber having a fiber axis being different than the transducer axis; a first lens comprising a ball lens disposed between the optoelectronic transducer and the optical fiber, a center of the first lens aligned to the optoelectronic transducer axis by the first alignment means; and a second lens between the optical fiber and the first lens, a center of the second lens aligned to the fiber axis by a second alignment means; wherein the first and second lenses form an optical relay which relays light between the center of the optoelectronic transducer and the center of the optical fiber, forming an efficient optical coupling between the optoelectronic transducer and the optical fiber, even though the transducer axis and the fiber axis do not coincide. In addition, a method for manufacturing the connector is also disclosed. | |
