Patent number: 9170382Abstract: A connector incorporating a module, in which an incorporated electrical component may be cooled efficiently and reliably, is provided. A transmission apparatus disposed inside a main body cover of a module-incorporating connector is provided with a ceramic board at which an electrical component and such are mounted. A metal cover touches an upper face of the electrical component. A portion of the metal cover is disposed in an insertion portion of the main body cover. Heat generated by the electrical component is propagated via the metal cover to the insertion portion of a first cover member. When the module-incorporating connector is connected to a socket of a device, the insertion portion is disposed inside an exterior case, in which temperature is controlled by an air conditioner, and cooling is performed reliably and efficiently.Type: GrantFiled: July 29, 2013Date of Patent: October 27, 2015Assignee: Molex, LLCInventors: Dean Richardson, Bogdan Andrei, Hideyuki Nasu

Patent number: 8254737Abstract: A tapered waveguide optical mode transformer (20) includes a tapered core formed on a planar substrate structure (16). To vertically taper the core (21), steps (22) are etched into the top surface of the core. The steps have depths and lengths along the optical axis of tapered waveguide that are selected to transform the optical mode characteristics of a desired optical fiber to the optical mode characteristics of a desired planar waveguide. The core can also be tapered horizontally to form a 2-D tapered waveguide. The tapered waveguide can be integrally included in planar lightwave circuits (PLCs) to reduce light coupling losses between optical fibers and the PLC waveguides.Type: GrantFiled: August 22, 2005Date of Patent: August 28, 2012Assignee: Molex IncorporatedInventors: Masum Choudhury, Moshe Oron, Thomas R.

Publication number: 20090154884Abstract: A fiber optic ferrule, preferably an MT-type ferrule, and connector design is provided that includes a unitary v-groove lens array (v-lens). The v-lens comprises a plurality of lenses and corresponding plurality of open v-grooves to align optical fibers with the plurality of lenses. Because the v-groove lens array is a unitary structure, high precision manufacturing is required for only the v-groove lens array, and not for other components forming the ferrule. A housing holds the v-groove lens array and preferably comprises a cantilever configured to retain the optical fibers substantially within their corresponding v-grooves. An opening in the housing allows an adhesive to be placed in contact with the housing, optical fibers and v-groove lens array thereby retaining the various components in a fixed relationship. A fiber optic connector may include the fiber optic ferrule in accordance with the present invention disposed within a suitable connector housing.Type: ApplicationFiled: April 4, 2006Publication date: June 18, 2009Inventors: Wenzong Chen, Malcolm H. Hodge, Iiya Makhlin, Dean Richardson
