Patent number: 11454759Abstract: In accordance with a method of forming a waveguide in a polymer film disposed on a substrate, a plurality of regions on a polymer film are selectively exposed to a first dosage of radiation. The polymer film is formed from a material having a refractive index that decreases by exposure to the radiation and subsequent heating. At least one region of the polymer film that was not previously exposed to the radiation is selectively exposing to a second dosage of radiation. The second dosage of radiation is less than the first dosage of radiation. The polymer film is heated to complete curing of the polymer film.Type: GrantFiled: August 22, 2018Date of Patent: September 27, 2022Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Linan Jiang, Stanley K. H. Pau, Robert A. Norwood, Thomas L. Koch

Patent number: 11456394Abstract: A photovoltaic (“PV”) module may comprise an array of freeform micro-optics and an array of PV cells. The PV module may be a flat panel with a nominal thickness smaller than the length and width of the flat panel. An array of lenses may be embedded in an array substrate. The lenses may be coupled to light pipes. The lenses may concentrate light through the light pipes to multi-junction cells. Diffuse light may be transferred through the array substrate to a silicon cell. The lenses and light pipes may be manufactured using a molding and drawing process.Type: GrantFiled: June 7, 2021Date of Patent: September 27, 2022Assignee: THE ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Stanley K.

Publication number: 20220244458Abstract: A method for establishing optical coupling between spatially separated first and second planar waveguides includes arranging an optical interconnect on the first planar waveguide. The optical interconnect has first and second end portions and an intermediate portion. Each of the end portions has an inverse taper. The second planar waveguide is arranged on the optical interconnect so that the second planar waveguide overlaps with one of the inverse tapered end portions but not the other inverse tapered end portion to thereby enable an adiabatic transition of an optical signal from the first planar waveguide to the second planar waveguide via the optical interconnect. The first and second planar waveguides have different refractive indices at an operating wavelength and the optical interconnect have a higher refractive index at the operating wavelength than the refractive indices of a core of the first planar waveguide and a core of the second planar waveguide.Type: ApplicationFiled: June 1, 2020Publication date: August 4, 2022Inventors: Thomas L. Koch, Erfan M. Fard, Roland Himmelhuber, Linan Jiang, Stanley K.H. Pau, Robert A. Norwood, Kyungjo Kim

Publication number: 20220105695Abstract: A method of forming an optical interconnect between first and second photonic chips located on an optical printed circuit board (OPCB) includes applying a coupling agent to a bonding surface of a flexible, freestanding polymer waveguide array film having at least one polymer waveguide disposed therein. The waveguide array film is placed onto the first and second photonic chips so that the waveguide array film extends over a gap and/or a step between the first and second photonic chips to thereby form a bonding interface between the bonding surface of the waveguide array film and the first and second photonic chips. The coupling agent is selected such that optical coupling between the first and second photonic chips arises simultaneously with formation of the bonding interface.Type: ApplicationFiled: January 17, 2020Publication date: April 7, 2022Inventors: Linan JIANG, STANLEY K. H. PAU, Robert A. NORWOOD, Thomas L. KOCH

Patent number: 11275208Abstract: A method of forming an optical interconnect between first and second photonic chips located on an optical printed circuit board includes applying a flexible, freestanding film onto the first and second chips so that the film extends over a gap and/or step between the chips. The film includes a photosensitive layer having a refractive index that decreases by exposure to radiation and a backing layer. The film is exposed to a flood exposure having a radiation dosage penetrating the backing layer and only a surface sublayer of the photosensitive layer. After curing the film, the backing layer is removed so that the photosensitive layer remains on the first and second chips. The photosensitive layer is selectively exposed to a second radiation dosage to define waveguide core(s) in unexposed regions of the photosensitive layer below the surface sublayer. The photosensitive layer is heated to cure the selectively exposed portions.Type: GrantFiled: February 26, 2019Date of Patent: March 15, 2022Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Linan Jiang, Stanley K.

Patent number: 7334630Abstract: Apparatus and methods according to the present invention utilize micropumps that are capable of generating high pressure and flow without moving mechanical parts and the associated generation of unacceptable electrical and acoustic noise, as well as the associated reduction in reliability. These micropumps are fabricated with materials and structures that improve performance, efficiency, and reduce weight and manufacturing cost relative to presently available micropumps. These micropumps also can allow for recapture of evolved gases and deposited materials, which may provide for long-term closed-loop operation. Apparatus and methods according to the present invention also allow active regulation of the temperature of the device through electrical control of the flow through the pump and can utilize multiple cooling loops to allow independent regulation of the spatial and temporal characteristics of the device temperature profiles. Novel enclosed microchannel structures are also described.Type: GrantFiled: May 25, 2005Date of Patent: February 26, 2008Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Kenneth E.
