Patent number: 6784372Abstract: An orthogonal electrical connector using a ball edge array includes one or more stackable fiber optic transceivers, wherein each transceiver includes an electrical substrate, and arrays of solder, which is in form of solder balls or solder paste. The solder is held in predetermined position adjacent to the electrical traces on both sides of the electrical substrate inserted into voids on the molded housing and aligned to contact the electrical traces on the motherboard. The electrical traces on the electrical substrate and the motherboard are located close enough so that the solder physically touches both parts during the soldering process. The solder is reflowed by heat, and the melted solder “wicks up” the electrical traces on the electrical substrate by surface tension.Type: GrantFiled: May 26, 2000Date of Patent: August 31, 2004Inventors: Albert T.

Patent number: 6429466Abstract: A method for growing a crystalline layer that includes a first material on a growth surface of a crystalline substrate of a second material, wherein the first material and the second material have different lattice constants. A buried layer is generated in the substrate such that the buried layer isolates a layer of the substrate that includes the growth surface from the remainder of the substrate. The second material is then deposited on the growth surface at a growth temperature. The isolated layer of the substrate has a thickness that is less than the thickness at which defects are caused in the crystalline lattice of the first material by the second material crystallizing thereon. The buried layer is sufficiently malleable at the growth temperature to allow the deformation of the lattice of the isolated layer without deforming the remainder of the substrate. The present invention may be utilized for growing III-V semiconducting material layers on silicon substrates.Type: GrantFiled: January 29, 2001Date of Patent: August 6, 2002Assignee: Agilent Technologies, Inc.Inventors: Yong Chen, Scott W.

Patent number: 6324002Abstract: An optical element constructed from a transparent support having a curved surface and a layer of a polarization-dependent film that is affixed to the curved surface. The polarization-dependent film passes linearly polarized light of a predetermined polarization while reflecting linearly polarized light having a polarization orthogonal to the predetermined polarization. The element is constructed by applying a layer of a transparent adhesive either to the layer of polarization-dependent film or to the curved surface. The support and layer of polarization-dependent film are then heated to a temperature above the temperature at which the polarization film can be deformed. The support and layer of polarization-dependent film are then pressed together so as to deform the layer of polarization-dependent film to cause the layer of polarization-dependent film to conform to the curved surface.Type: GrantFiled: October 26, 1999Date of Patent: November 27, 2001Assignee: Agilent Technologies, Inc.Inventors: Pierre H.
