Patent number: 9143259Abstract: A system and method for optical switching of networks in a multi-node computing system with programmable magneto-optical switches that enable optical signal routing on optical pathways. The system includes a network of optical links interconnecting nodes with switching elements that are controlled by electrical control signals. Data transmission is along the optical links and an optical pathway is determined by the electrical control signals which are launched ahead of optical signal. If links are available, an optical pathway is reserved, and the electrical signal sets the necessary optical switches for the particular optical pathway. There is thereby eliminated the need for optical-electrical-optical conversion at each node in order to route data packets through the network. If a link or optical pathway is not available the system tries to find an alternative path. If no alternative path is available, the system reserves buffering. After transmission, all reservations are released.Type: GrantFiled: August 29, 2012Date of Patent: September 22, 2015Assignee: International Business Machines CorporationInventors: Maurice McGlashan-Powell, Valentine Salapura

Patent number: 8178153Abstract: A heat transfer control structure and a method for fabrication thereof includes at least one heat transfer control layer interposed between and contacting a heat source material and a heat sink material. The at least one heat transfer control layer is selected predicated upon thermal phonon spectra overlap between the heat source material, the at least one heat transfer control layer and the heat sink material. The at least one heat transfer control layer may enhance or retard heat transfer between the heat source material and the heat sink material. The at least one heat transfer control layer may be selected based upon a value of a thermal phonon correlating parameter such as a Debye temperature, a density or a lattice constant.Type: GrantFiled: March 31, 2006Date of Patent: May 15, 2012Assignee: International Business Machines CorporationInventors: Claudius Feger, Maurice McGlashan-Powell, Ijeoma M.

Publication number: 20090080833Abstract: A single-mode optical waveguide with a core, surrounded by a cladding consisting of an inner soft layer and an outer harder layer is described. The outer layer has a grating structure on its inner surface, whose spatial frequency is the same as that of the guided mode. The thickness of the inner cladding is sufficient to keep the grating outside the mode field in undeformed regions of the waveguide, so that normally no out-coupling of the light results. Connections are made by crossing two such waveguides at an angle and pressing them together. This results in deformation of the two waveguides such that the gratings are brought into proximity with the cores. Light is coupled out of one waveguide and into the other in the deformed region, resulting in a self-aligning optical connection. The out-coupled light propagates normal to the waveguide axis, so errors in the crossing angle cause little change in efficiency.Type: ApplicationFiled: August 9, 2008Publication date: March 26, 2009Inventors: Claudius Feger, Philip O. D. Hobbs, Maurice McGlashan-Powell

Patent number: 7486845Abstract: A method in effectuating the redirection of light which is propagated within a waveguide, and which eliminates the necessity for a bending of the waveguide, or the drawbacks encountered in directional changes in propagated light involving the need for sharp curves of essentially small-sized radii, which would resultingly lead to excessive losses in light. In this connection, the method relates to the fabricating and the provision of a wire-grid polarization beam splitter within an optical waveguide, which utilizes a diblock copolymer template to formulate the wire-grid.Type: GrantFiled: October 11, 2007Date of Patent: February 3, 2009Assignee: International Business Machines CorporationInventors: Charles T. Black, Gian-Luca Bona, Timothy J. Dalton, Nicholas C. M. Fuller, Roland Germann, Maurice McGlashan-Powell, Chandrasekhar Narayan, Robert L. Sandstorm
