  • Publication number: 20180231696
    Abstract: A method for modifying the refractive index of an optical polymeric material. The method comprises continuously irradiating predetermined regions of an optical, polymeric material with femtosecond laser pulses to form a gradient index refractive structure within the material. The optical polymeric material can include a photosensitizer to increase the photoefficiency of the two-photo process resulting in the formation of the observed refractive structures. An optical device includes an optical, polymeric lens material having an anterior surface and posterior surface and an optical axis intersecting the surfaces and at least one laser-modified, GRIN layer disposed between the anterior surface and the posterior surface and arranged along a first axis 45° to 90° to the optical axis.

  • Publication number: 20180206979
    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: 9995880
    Abstract: An optical communications module is provided that has WDM capabilities for increased bandwidth and that is suitable for use with single mode optical fiber or multimode optical fiber. The module can be configured to have both WDM and BiDi functionality to further increase bandwidth and can have a single- or multi-channel configuration. The module has an integrally-formed body having an optical port and portions of an optical coupling system that are integrally formed in the body. The optical port is adapted to mate with an end of an optical fiber cable that holds one or more ends of one or more optical fibers, depending on whether the module is a single-channel or multi-channel module. The optical coupling system couples light between an end or ends of one or more optical fibers and one or more optoelectronic devices in a way that reduces back reflection and mode partition noise.

  • Patent number: 9997343
    Abstract: An electrostatic ion trap for mass analysis includes a first array of electrodes and a second array of electrodes, spaced from the first array of electrode. The first and second arrays of electrodes may be planar arrays formed by parallel strip electrodes or by concentric, circular or part-circular electrically conductive rings. The electrodes of the arrays are supplied with substantially the same pattern of voltage whereby the distribution of electrical potential in the space between the arrays is such as to reflect ions isochronously in a flight direction causing them to undergo periodic, oscillatory motion in the space, focused substantially mid-way between the arrays. Amplifier circuitry is used to detect image current having frequency components related to the mass-to-charge ratio of ions undergoing the periodic, oscillatory motion.

  • Publication number: 20180150492
    Abstract: User data of different snapshots for the same virtual disk are stored in the same storage object. Similarly, metadata of different snapshots for the same virtual disk are stored in the same storage object, and log data of different snapshots for the same virtual disk are stored in the same storage object. As a result, the number of different storage objects that are managed for snapshots do not increase proportionally with the number of snapshots taken. In addition, any one of the multitude of persistent storage back-ends can be selected as the storage back-end for the storage objects according to user preference, system requirement, snapshot policy, or any other criteria. Another advantage is that the storage location of the read data can be obtained with a single read of the metadata storage object, instead of traversing metadata files of multiple snapshots.

  • Publication number: 20180034993
    Abstract: A communication method is provided between a chip and an imaging device. Accordingly, the chip receives a clock pulse signal from the imaging device via a clock line; and receives a READ instruction from the imaging device via a data line. Within one clock pulse signal period, the chip transmits at least one bit of implicit data and one bit of master data that are stored in an internal memory to the data line within different time slots, respectively, and the imaging device collects data from the data line while the chip is transmitting the master data to the data line. Further, the chip receives a WRITE instruction from the imaging device via the data line, wherein the chip receives master data sent from the imaging device, writes the master data into the memory arranged in the chip, and updates the implicit data stored in the memory.

  • Patent number: 9786485
    Abstract: A mass analyser comprises a pair of electrode arrays. Each array has a set of focusing electrodes which are supplied, in use, with voltage to create an electrostatic field in a space between the electrode arrays causing ions to undergo periodic, oscillatory motion in the space, ions passing between electrodes of the sets of focusing electrodes and being repeatedly focused at a center plane, mid-way between the electrode arrays. At least one electrode of each set of focusing electrodes has an electrode surface closer to the center plane than the electrode surfaces of other electrodes of the same set. The analyzer may be an ion trap mass analyser or a multi-turn ToF mass analyzer.

  • Publication number: 20170156931
    Abstract: By adapting femtosecond micromachining approaches developed in hydrogels, we can perform Intra-tissue Refractive Index Shaping (IRIS) in biological tissues. We reduced femtosecond laser pulse energies below the optical breakdown thresholds to create grating patterns that are associated with a change in the refractive index of the tissue. To increase two-photon absorption, we used a two (or more)-photon-absorbing chromophore.
