Patent number: 6939648Abstract: The optical article of the invention, e.g., holographic recording medium or polymeric waveguide, is formed by mixing a matrix precursor and a photoactive monomer, and curing the mixture to form the matrix in situ. The reaction by which the matrix precursor is polymerized during the cure is independent from the reaction by which the photoactive monomer is polymerized during writing of data. In addition, the matrix polymer and the polymer resulting from polymerization of the photoactive monomer are compatible with each other. Use of a matrix precursor and photoactive monomer that polymerize by independent reactions substantially prevents cross-reaction between the photoactive monomer and the matrix precursor during the cure and inhibition of subsequent monomer polymerization. Use of a matrix precursor and photoactive monomer that result in compatible polymers substantially avoids phase separation. And in situ formation allows fabrication of articles with desirable thicknesses.Type: GrantFiled: April 3, 2002Date of Patent: September 6, 2005Assignee: InPhase TechnologiesInventors: Lisa Dhar, Arturo Hale, Howard Edan Katz, Marcia Lea Schilling, Melinda Lamont Schnoes

Patent number: 6322932Abstract: High storage densities using a holographic system are achievable using a stratified medium while maintaining a relatively high selectivity upon reconstruction of the stored images. Such combination of high density and high selectivity is achievable by employing a stratified medium and a recording process where selectivity does not vary with recording thickness.Type: GrantFiled: August 15, 1996Date of Patent: November 27, 2001Assignee: Lucent Technologies Inc.Inventors: Vicki L. Colvin, Kevin Richard Curtis, Alexander Lowe Harris, Howard Edan Katz, Marcia Lea Schilling, William Larry Wilson

Patent number: 6165648Abstract: A thick holographic recording medium suitable for use in multiplex holography is prepared from a solution of a bi-functional oligomer and a mono-functional monomer. Precuring, possibly at the same radiation wavelength used for recording, cross-links the oligomer, thereby creating a host for the recording monomer.Type: GrantFiled: September 18, 1998Date of Patent: December 26, 2000Assignee: Lucent Technologies Inc.Inventors: Vicki L. Colvin, Alexander Lowe Harris, Howard Edan Katz, Marcia Lea Schilling

Patent number: 6160645Abstract: A holographic medium uses a photosensitive polymer medium. The shelf life of the photosensitive polymer medium is improved by hermetically sealing the polymer between glass plates. The hermetic seal is designed so that high T.sub.g materials, or solder, can be used as the sealant without damage to the polymer already contained between the plates. The hermetic seal comprises metal foils attached to the plates with the edges thereof extending away from the plates in tab-like fashion. The foils are attached prior to filling the assembly with polymer. After filling, the outer edges of the foil tabs are the sealed with local heating away from the site of the polymer, or crimped using mechanical crimping.Type: GrantFiled: October 26, 1999Date of Patent: December 12, 2000Assignee: Lucent Technologies Inc.Inventors: Edwin Arthur Chandross, Venkataram Reddy Raju, Marcia Lea Schilling, Jeffrey Linn Bream

Patent number: 6016696Abstract: A method for determining a volume change of a viscous liquid during a physical or chemical process is disclosed. The volume change of the viscous liquid is determined by confining a layer of a viscous liquid on a portion of a rigid body and then measuring the linear (one dimensional) displacement of a planar surface formed thereon, as the viscous liquid undergoes the physical or chemical process. The surface of the layer of the viscous liquid is planar relative to the rigid body.Type: GrantFiled: September 25, 1998Date of Patent: January 25, 2000Assignee: Lucent Technologies Inc.Inventors: Harvey Edward Bair, Arturo Hale, Marcia Lea Schilling

Patent number: 5904983Abstract: An optical fiber protected from degradation caused by corrosion from environmental fluids. The optical fiber includes a core-cladding assembly surrounded with a thin quasi metal oxide film (preferably .about.10 nm in depth). Over time, particularly under the influence of the elevated temperatures, the initially deposited reagents of the thin film oxidize or hydrolyze, removing the organic components, and bonding a quasi metal oxide film on the surface of the cladding. The resulting film significantly retards corrosion by blocking the environmental fluids from reacting with flaws in the cladding surface of the fiber, thus improving the mechanical performance and reliability of the optical fiber. In addition, the thin film protects the fiber against incidental abrasions.Type: GrantFiled: May 23, 1997Date of Patent: May 18, 1999Assignee: Lucent Technologies Inc.Inventors: Maureen Gillen Chan, Daryl Inniss, Howard Edan Katz, Valerie Jeanne Kuck, Marcia Lea Schilling

Patent number: 5725996Abstract: A novel resist composition is disclosed. The resist composition is used in a lithographic process for device fabrication. The resist composition contains a polymer with phosphorus ester moieties. These moieties make the resist composition suitable for use in a variety of lithographic processes for fabricating integrated circuits.Type: GrantFiled: October 22, 1996Date of Patent: March 10, 1998Assignee: Lucent Technologies Inc.Inventors: Francis Michael Houlihan, Howard Edan Katz, Marcia Lea Schilling
