  • Publication number: 20230258871
    Abstract: A method for fiber-to-chip coupling is disclosed. The method comprises providing a photonic integrated circuit (PIC) that includes a substrate, a cladding layer on the substrate, and at least one waveguide embedded in the cladding layer, wherein the at least one waveguide has a waveguide interface. An optical fiber is positioned adjacent to the PIC, wherein the optical fiber has a fiber interface, and the fiber interface is aligned with the waveguide interface. A flowable inorganic oxide in liquid form is added to an area between the fiber interface and the waveguide interface. Thereafter, heat is applied to the area between the fiber interface and the waveguide interface for a period of time to cure the inorganic oxide, such that the optical fiber is coupled to the PIC. The cured inorganic oxide has a refractive index that substantially matches the refractive indices of the cladding layer and the optical fiber.

  • Patent number: 11536908
    Abstract: A multilayer waveguide coupler comprising a first grating and a second grating is provided. Each first copropagating waveguide of the first grating has a first periodically modulated width. Each second copropagating waveguide of the second grating has a second periodically modulated width. The second grating is positioned so that a phase offset is present between the first periodically modulated width of the first copropagating waveguides and the second periodically modulated width of the second copropagating waveguides. The grating spaced distance and phase offset are selected so that light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the first direction interferes constructively to form the first light beam and light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the second direction interferes destructively.

  • Patent number: 9111024
    Abstract: A portable medical treatment device is designed to be placed on or near a patient when the patient is moved. The device communicates with a database that stores patient profiles and/or treatment protocols. Based on input patient information, the device communicates with the database and loads a patient profile and/or treatment protocol. The device evaluates data entered by a user according the patient profile and/or treatment protocol to determine metrics, and the determined metrics are compared with parameters to determine whether the entered data is within acceptable limits. The device tags and displays the entered data in a manner that reflects whether it was within the acceptable limits.

  • Publication number: 20090112928
    Abstract: In one example embodiment, a system and method is disclosed as including generating a translation rule file describing a first rule to be used to translate a record definition file. An operation may then be performed that maps the record definition file, using the first rule, to generate a record definition rule file describing a second rule used to translate transaction data. Further, an operation may be performed that transforms the transaction data, using the second rule, to generate a fulfillment file. In some example embodiments, the first rule is written in an eXtensible Markup Language (XML) and describes a data type. Further, this data type may include a description of another mapping from a first data type to a second data type. In some example cases, the record definition file is written in XML, and describes a file format associated with a client.
