Patent number: 8062900Abstract: A microplate for use within an interrogation system and a method of using the microplate are disclosed. The microplate contains within the bottom of each well, an optical waveguide grating based sensor. Approximate to each sensor is a mask having an aperture of predetermined size. The aperture regulates the light that enters and exits the sensor upon successive scans and ensures repeatable readings from the sensor. In an extended embodiment, a method of detection is disclosed that utilizes a launch and receive system while employing the aforementioned microplate.Type: GrantFiled: May 17, 2006Date of Patent: November 22, 2011Assignee: Corning IncorporatedInventor: Robert A.

Patent number: 7471435Abstract: The present invention provides an apodization mask that narrows the central lobe of an optical image of a point in a focusing system and suppresses the amplitudes of the sidelobes of the image that are within a predetermined radius of the central axis of the sidelobes, thereby improving resolution of point objects that are relatively close together and presenting better images of small objects.Type: GrantFiled: February 10, 2005Date of Patent: December 30, 2008Inventor: Robert A.

Patent number: 6943889Abstract: An athermal interferometric wavelocker is disclosed having a beam splitter combiner and a first arm of a first material having a first refractive index, a first length, and a first coefficient of expansion; and, a second arm of a second material having a second refractive index, a second length, and a second coefficient of expansion. The refractive indices, lengths and coefficients of expansion of the first arm and the second arm are selected to provide a substantially athermal structure operating at ambient temperatures. The first arm and second arm have inner end faces that meet adjacent faces of the beam splitter and combiner. The first and second arms are of a different optical path length such that light launched into the beam splitter and combiner, interferes upon recombining, and is output from a combiner output port to provide a wavelocker signal having a detectable characteristic which varies with wavelength.Type: GrantFiled: July 29, 2003Date of Patent: September 13, 2005Assignee: JDS Uniphase CorporationInventor: Robert Modavis

Publication number: 20050018981Abstract: The invention relates to a receiver optical sub-assembly (ROSA) for use in an optical transceiver to convert optical signals transmitted along an optical fiber into electrical signals for use by a host device. Conventionally, light exiting the optical fiber inside an optical coupler of the ROSA encounters a refractive index mismatched interface, e.g. fiber/air, causing a portion of the light to be reflected directly back into the fiber. To minimize back reflections at the interface with the optical fiber, an optical insert is provided having an index of refraction matching that of the optical fiber, thereby moving the mismatched interface remote from the end of the fiber to an interface of the optical insert and a lens, to which the optical insert is attached.Type: ApplicationFiled: July 16, 2004Publication date: January 27, 2005Applicant: JDS Uniphase CorporationInventors: Robert Modavis, Timothy Douglas Goodman, Roger Lindquist, Chris Hart, William Hogan

Patent number: 6694075Abstract: Filter gratings are formed in optical waveguides having photosensitive cores by exposing the cores to actinic radiation in the form of interfering beams having peak intensities that are relatively displaced along an optical axis of the waveguides. Each of the interfering beams has a single-lobed intensity profile and a degree of spatial coherence required to achieve a desired fringe contrast between the two relatively displaced beams. Index modulations in the photosensitive core match the illumination (interference) pattern of the radiation. The relative displacement of the interfering beams reduces side lobes of the gratings' spectral responses by leveling the average refractive index of the index modulations. A second exposure with the two beams but without the beams' interference effects further levels the average refractive index.Type: GrantFiled: June 30, 1999Date of Patent: February 17, 2004Assignee: Corning IncorporatedInventors: Vikram Bhatia, Thomas A. Cook, Robert A. Modavis, Christopher D. Robson
