Publication number: 20080165521Abstract: A three-dimensional architecture chip includes a base chip including a unit integrated thereon and configured to perform electrical signal operations. An active layer is separately fabricated from the base layer. The active layer includes a component to service the unit of the base chip. The active layer is bonded to the base chip such that the component is aligned in vertical proximity of the unit. An electrical connection connects the unit to the component through vertical layers of at least one of the base chip and the active layer.Type: ApplicationFiled: January 9, 2007Publication date: July 10, 2008Inventors: KERRY BERNSTEIN, Paul William Coteus, Ibrahim (Abe) M. Elfadel, Philip George Emma, Kathryn W. Guarini, Thomas Fleischman, Allan Mark Hartstein, Ruchir Puri, Mark B. Ritter, Jeannine Madelyn Trewhella, Albert M. Young

Patent number: 6873799Abstract: An optical signal transceiver subassembly is mounted on a lead frame for further attachment to an electronic printed circuit board. The optical subassembly is comprised of a solid-state laser, a pair of photo-detectors, an over-mold of transparent material having shapes forming the exposed surface thereof, the surface and a selective silvering of a portion thereof defining a beam-splitter mirror and an interior reflective focusing surface, preferably in the shape of a partial cylindrical surface. The beam-splitter mirror is lightly silvered and the cylindrical surface is silvered to enhance the reflection of the laser beam. The optical subassembly is further enclosed with a housing incorporating a pair of lenses and alignment pins. The lenses focus the data stream of optical light signals onto the end of the outgoing optical fiber and the data stream of optical light signals from the incoming optical fiber onto and through the beam-splitter and onto a first photo-detector.Type: GrantFiled: June 20, 2001Date of Patent: March 29, 2005Assignee: JDS Uniphase CorporationInventors: Mitchell Simmons Cohen, David Peter Gaio, William K. Hogan, Glen Walden Johnson, Jeannine Madelyn Trewhella

Patent number: 6713827Abstract: A method is provided for the manufacture of micro-structures, such as micro-electromechanical structures (MEMS) or silicon optical benches (SiOB). The method includes using a single mask to pattern two or more cavity areas to be etched into a substrate in different etching steps, and then selectively choosing the cavity areas for etching. In a preferred embodiment, the method includes patterning a substrate to identify a plurality of cavity areas to be etched into the substrate and filling at least one of the cavity areas with a distinctive filler material. Filler material is chemically distinctive in the sense that it can be etched selectively with respect to the other filling materials. At least one of the cavity areas containing a distinctive filler material is then chosen based at least in part on the distinctive filler material. The chosen cavity area is then etched.Type: GrantFiled: January 27, 2003Date of Patent: March 30, 2004Assignee: International Business Machines CorporationInventors: Guy Moshe Cohen, Steven Alan Cordes, Joanna Rosner, Jeannine Madelyn Trewhella

Patent number: 6527460Abstract: A fiber optic arrangement includes a chip, and a first light emitter and a second light emitter formed on the chip. A guide is formed on the chip and in registration with an active region of the second light emitter. An optical fiber is coupled to the second light emitter for transmitting light from the second light emitter. The guide aligns the optical fiber relative to the active region of the second light emitter. A light-sensing device is provided. An optical element transmits light emitted from the first light emitter to the light-sensing device for controlling an output optical power of at least the second light emitter.Type: GrantFiled: June 27, 2001Date of Patent: March 4, 2003Assignee: International Business Machines CorporationInventors: Mitchell Simmons Cohen, David Peter Gaio, William K.

Patent number: 6502999Abstract: An opto-electronic module is housed in a hermetically sealed housing which is fabricated on a base member of solderable material to which a side wall structure is soldered. A cover is similarly provided that either is soldered to the top open end of the housing at the edge of the housing wall structure or is a cup-shaped member that slides over the wall structure and is soldered at the juxtaposed faces of the walls of the cover and the wall structure. Overlapping slots co-align to form a passage through which optical fibers may pass through the walls. The hermetic seal of the housing prevents the internal contamination of the module by water vapor, particulate matter or other contaminants.Type: GrantFiled: September 4, 2001Date of Patent: January 7, 2003Assignee: JDS Uniphase CorporationInventors: Mitchell Simmons Cohen, David Peter Gaio, William K. Hogan, Steven Paul Ostrander, Sudipta Kumar Ray, Jeannine Madelyn Trewhella
