Publication number: 20110222567Abstract: A TO-can header assembly is provided that has improved heat dissipation and thermal resistance characteristics. The TO-can header assembly includes a relatively large ceramic heat dissipation block that functions as both a carrier for the laser diode and as a heat dissipation device. The ceramic heat dissipation block is in contact with the upper mounting surface of the header to allow a relatively large amount of heat to quickly pass from the laser diode through the heat dissipation block and into the upper mounting surface of the header. The cylindrical side wall of the header is smooth, rather than notched, and at least a substantial portion of the smooth cylindrical side wall is in continuous contact with an external heat sink device. Heat moves rapidly from the header into the external heat sink device where it is dissipated, thereby reducing the thermal resistance of the header.Type: ApplicationFiled: March 9, 2010Publication date: September 15, 2011Applicant: AVAGO TECHNOLOGIES FIBER IP (SINGAPORE) PTE. LTD.Inventors: Marco Scofet, Luigi Tallone, Stefano Genisio

Patent number: 7804867Abstract: A laser mounted in a casing is driven by and mounted close to its driving circuit. To reduce the effect on the laser of heat generated by the driver circuit, the casing includes a passive heat sink element on which the driver circuit is mounted whereby heat generated by the driver is dissipated by the passive heat sink element.Type: GrantFiled: July 3, 2008Date of Patent: September 28, 2010Assignee: Avago Technologies Fiber IP (Singapore) Pte. Ltd.Inventors: Marco Scofet, Enrico Di Mascio, Cristiana Contardi, Stefano Genisio

Patent number: 7711220Abstract: A fiber stub assembly is provided that has a cladding layer that is reduced in diameter near the end of the stub into which light is launched from a light source. The portion of the stub having the cladding layer with the reduced diameter is surrounded by a light-absorbing material that is in contact with the inner surface of the ferule and with the outer surface of the cladding layer. The light-absorbing material and the outer surface of the cladding layer have indices of refraction that are matched, or very close to one another, such that any modes of light that are propagating in the cladding layer that impinge on the interface propagate into the light-absorbing material and are absorbed thereby. The reduced diameter of the cladding layer and the surrounding light-absorbing material form a pin hole opening through which light is received.Type: GrantFiled: February 13, 2008Date of Patent: May 4, 2010Assignee: Avago Technologies Fiber IP (Singapore) Pte. Ltd.Inventors: Marco Scofet, Cristiana Contardi, Luigi Tallone

Patent number: 7261473Abstract: An optical sub assembly for receiving an optical fiber transmission line for coupling to an optical device, to a receptacle for use in such a sub assembly and to a method of manufacture of such a sub assembly. The optical sub assembly preferably provides electrical isolation between a receptacle having a nose for receiving the optical fiber and a package housing an optical device. The nose houses a ferrule containing a fiber stub which may be optically aligned with an optical device housed in a package before securing the receptacle to the package. The electrical insulation is provided between the nose and the package by a sleeve extending along a middle portion of the ferrule and an insulating portion positioned between the sleeve and the nose.Type: GrantFiled: December 23, 2002Date of Patent: August 28, 2007Assignee: Avago Technologies Fiber IP (Singapore) Pte LtdInventors: Martyn Owen, Jason Gregory, Marco Scofet, Enrico Di Mascio
