  • Patent number: 10806567
    Abstract: A method for modifying the refractive index of an optical, polymeric material. The method comprises irradiating select regions of the optical, polymeric material with a focused, visible or near-IR laser having a pulse energy from 0.05 nJ to 1000 nJ. The irradiation results in the formation of refractive optical structures, which exhibit little or no scattering loss. The method can he used to modify the refractive index of an intraocular lens following the surgical implantation of the intraocular lens in a human eye. The invention is also directed to an optical device comprising refractive optical structures, which exhibit little or no scattering loss and are characterized by a positive change in refractive index.

  • Patent number: 10776725
    Abstract: A method for implementing a graphical modeling tool in a web-based environment is disclosed herein. In one embodiment, such a method may include enabling a user to import, into a web-based environment, a domain meta model comprising a number of meta model elements. The method may further enable the user to associate the meta model elements with graphical representations in the web-based environment, thereby allowing the user to create palette elements. The user may then assemble the palette elements on a canvas to create a diagram. This diagram may be converted into an instance of the domain meta model. This instance may be validated for conformance with the rules and constraints associated with the domain meta model. A corresponding apparatus and computer program product are also disclosed and claimed herein.

  • Patent number: 10649157
    Abstract: A freeform DOE for use in an optical transmitter and a method of designing and manufacturing the DOE are provided. The freeform DOE is capable of achieving the same, or nearly the same, functionality as that of a glass DOE, but has a design that has been transformed to make the surface profile of the DOE compatible with a molding process that can be used to manufacture the DOE with high quality at low costs. The method of designing and manufacturing the DOE includes preselecting a CGH that will obtain a target freeform DOE design, using a preselected smoothing function to smooth the surface profile of the target freeform DOE design to transform the design into a DOE design that is compatible with a molding process, and using a fabrication process to manufacture a freeform DOE that is based on the transformed DOE design.

  • Patent number: 10451889
    Abstract: An optics system is provided that comprises a glass-based diffractive optical element (DOE) for coupling an optical signal passing out of an optical waveguide into a photodetector. The glass-based DOE improves optical link performance by performing one or more of shortening a response time of a photodetector, preventing an overloading condition of the photodetector from occurring and managing back reflection of light from the photodetector. The glass-based DOE is relatively inexpensively to manufacture and is reliable over a wide range of temperatures.

  • Patent number: 10381208
    Abstract: A method of processing an image charge/current signal representative of trapped ions undergoing oscillatory motion. The method includes: identifying a plurality of fundamental frequencies potentially present in the image charge/current signal based on an analysis of peaks in a frequency spectrum corresponding to the image charge/current signal in the frequency domain, wherein each candidate fundamental frequency falls in a frequency range of interest; deriving a basis signal for each candidate fundamental frequency using a calibration signal; and estimating relative abundances of ions corresponding to the candidate fundamental frequencies by mapping the basis signals to the image charge/current signal. At least one candidate fundamental frequency is calculated using a frequency associated with a peak that falls outside the frequency range of interest and that has been determined as representing a second or higher order harmonic of the candidate fundamental frequency.
