Patent number: 11133639Abstract: Systems and methods described herein provide a thermally compensated waveguide structure having a thermal index profile configured to correct thermal aberrations caused by temperature gradients in a fast axis direction and/or correct other forms of distortions in an output beam generated by the waveguide structure. The waveguide structure includes a core region, one or more cladding, and one or more heat sinks. A geometry of these portions with respect to each other can provide a cold refractive index profile such that a cold refractive index value of a portion of the core region is less than a cold refractive index value of at least one of the one or more cladding regions. Responsive to thermal compensation, the cold refractive index profile is modified, through addition of a thermal index profile, to form a hot index profile having attributes including good overlap of the fundamental mode with the gain profile and mode clean-up through gain discrimination against higher order modes.Type: GrantFiled: July 24, 2018Date of Patent: September 28, 2021Assignee: Raytheon CompanyInventors: Friedrich Strohkendl, Makan Mohageg, Michael Ushinsky

Patent number: 10511135Abstract: An apparatus includes a PWG having a core region and a cladding layer. The amplifier is configured to receive pump light. The core region is configured to amplify an input beam using energy from the pump light to generate an amplified output beam. The apparatus also includes a cooling fluid configured to cool the core region. The cooling fluid has a lower refractive index than the core region and the cladding layer in order to support guiding of the input beam and pump light within the amplifier. The amplifier also includes first and second endcaps attached to opposite faces of the core region and cladding layer. The core region, cladding layer, and endcaps collectively form a monolithic fused structure. Each endcap has a major outer surface that is larger in area than a combined area of the faces of the core region and cladding layer to which the endcap is attached.Type: GrantFiled: December 19, 2017Date of Patent: December 17, 2019Assignee: Raytheon CompanyInventors: Friedrich P. Strohkendl, Michael Ushinsky, Jeffrey P. Yanevich

Patent number: 10023290Abstract: A method of improving optical characteristics of an optical window operating in a flow of fluid and having first and second panes of optically transmissive material—each having an edge adjacent to, parallel with, and at least partially coextensive with each other—is described herein. The method includes inserting a thermally conductive blade between two adjacent edges of the first and second panes of optically transmissive material; and lifting an adverse flow stagnation zone forward of the optical window by protruding the thermally conductive blade into the flow of fluid from an outer surface of the panes of the optical window.Type: GrantFiled: August 16, 2017Date of Patent: July 17, 2018Assignee: Raytheon CompanyInventors: David A.

Publication number: 20180093917Abstract: A molding composite includes mica flakes and a eutectic glaze. The composite allows making of lead-free parts for use in a variety of situations, such as electrical insulators for supporting electrically-conductive parts, such as electrodes, for electrical devices. The molded composite material can be used mold around such electrically-conductive parts, supporting them and/or providing hermetic seals around the parts. Other possible uses include substrates for electronic circuits, and housings for parts, such as electro-optical parts. The molding composite is heated under elevated pressure to liquefy the eutectic glaze, causing it to coat the mica flakes. After the composite is put into a desired shape it is solidify, for example by compressing the molding composite at a constant temperature until the eutectic glaze solidifies, followed by cooling of the molding composite.Type: ApplicationFiled: October 3, 2016Publication date: April 5, 2018Inventors: Michael Ushinsky, Sunder S. Rajan, Scott T. Turner, Isaac C. Chen

Patent number: 9606311Abstract: A method includes obtaining a substrate having at least one exposed metal surface. The method also includes electro-depositing metal onto the at least one exposed metal surface of the substrate and around at least a portion of an optical fiber to secure the optical fiber to the substrate. The substrate and the electro-deposited metal are configured to remove heat from the optical fiber. The method could further include electro-depositing metal around a sacrificial material and removing the sacrificial material to form at least one cooling channel through the electro-deposited metal. The optical fiber could include a polymer coating, where a portion of the polymer coating is removed at an end of the optical fiber. The substrate and the electro-deposited metal could be faceted at an input of the optical fiber and at an output of the optical fiber. The optical fiber could have a coiled arrangement on the substrate.Type: GrantFiled: December 18, 2013Date of Patent: March 28, 2017Assignee: Raytheon CompanyInventors: Joseph L.
