Patent number: 8638493Abstract: An optical coupler for coupling optical-pump power into a multimode fiber configured to transport an optical space-division-multiplexed (SDM) signal, the coupling being performed in a manner that enables amplification of the SDM signal in the multimode fiber via a stimulated-emission process or a stimulated Raman-scattering process. The optical coupler can be a part of an optical transmitter configured for co-directional pumping, an optical receiver configured for contra-directional pumping, or a relay station disposed within an optical communication link and configured for either type of pumping. The optical coupler can advantageously be used, e.g., to offset the different degrees of attenuation to which the SDM-signal components corresponding to different guided modes of the multimode fiber are subjected to therein.Type: GrantFiled: September 16, 2011Date of Patent: January 28, 2014Assignee: Alcatel LucentInventor: Roland Ryf

Patent number: 8638495Abstract: An embodiment of the present invention provide for an optical microscope apparatus including a light source, a base unit, a rotary monochromatic dispersion unit, a condenser, a stage, an objective, a tubular assembly and an ocular assembly. In a preferred embodiment, light travels from the light source sequentially through each of these seven components, producing an image of the contents of a slide on the stage to a user looking through the ocular assembly. In the base unit, in place of a standard mirror which would direct the light vertically up into the scope along the z-axis, a right angle piece of single crystal Calcite, known as Iceland Spar is used, which has a birefringent affect upon the light as it passes up through the scope.Type: GrantFiled: March 16, 2012Date of Patent: January 28, 2014Assignee: TBC Optics, LLCInventors: Stanley A Truman, Jr., W.

Patent number: 8638496Abstract: Liquid lens cells are used in a compound variable power optical system that forms an intermediate image between the object and the final image. A first variable power optical component is located between the object and an intermediate real image. The first variable power optical component varies power to change the magnification of the intermediate real image. A second variable power optical component is located between the intermediate real image and the final image.

Patent number: 8638498Abstract: In embodiments of eyebox adjustment for interpupillary distance, a first optical lens receives light of an image from a display optic at a projected orientation of the light, and the first optical lens deviates the light of the image by a deviation angle from the projected orientation of the light. A second optical lens receives the light of the image from the first optical lens at the deviation angle, and the second optical lens alters the deviated light of the image back to the projected orientation of the light for viewing the image. Left and right eyeboxes align with respective left and right eyes that view the image, and a distance between the left and right eyeboxes approximately correlates to an interpupillary distance between the left and right eyes. The light of the image can be laterally shifted to increase or decrease the distance between the left and right eyeboxes.Type: GrantFiled: January 4, 2012Date of Patent: January 28, 2014Inventors: David D.

Patent number: 8638500Abstract: A lens, such as a lens for use in a wafer-level camera, is made by forming a polymeric material with at least one master to form a pre-final lens. The pre-final lens forms a majority of a final volume of the lens. The pre-final lens is allowed to harden, during which it may sag or shrink. An aliquot of polymeric material is added to the lens and formed with the same master with a spacer, or with a second master, to form a first surface layer that provides correction between the pre-final lens shape and a final desired lens shape. In an embodiment, the surface layer has similar or identical index of refraction to the pre-final lens. In an embodiment the lens is formed on a substrate. In an embodiment, a send master, or master pair, are used to form a lens having upper and lower curvature, with a second aliquot of polymeric material forming a second surface layer on a surface of the lens opposite to the first surface layer.Type: GrantFiled: February 9, 2011Date of Patent: January 28, 2014Assignee: OmniVision Technologies, Inc.Inventors: Dennis J.
