Abstract: A method for fabricating an optical waveguide comprises: providing a sample of lithium niobate doped with magnesium oxide and having at least one grating of periodic domain inversion defined therein; applying a layer of metallic zinc to a surface of the sample over the at least one grating using sputter deposition; heating the sample in an atmosphere of pure oxygen to cause the zinc to indiffuse into the lithium niobate to form a waveguiding layer of increased refractive index under the surface of the sample; and using a dicing blade to cut two substantially parallel channels along a length direction of the at least one grating, to define a ridge waveguide between the two channels.

Abstract: An integrated reference electrode for use in an electrochemical measurement system, comprising: a reference electrode in combination with a hygroscopic hydrogel electrolyte impregnated and contained in a porous framework, wherein the hygroscopic hydrogel electrolyte is adapted to contact the reference electrode when in a hydrated state. Also, an ion selective membrane with an aromatic epoxy polymer made from one or more monomers having at least one epoxide group, and a chloride salt or a silver—silver chloride physically trapped in the aromatic epoxy polymer. On contact with water the aromatic epoxy polymer forms a network of channels for ion exchange. The membrane may be used between an electrolyte and an external fluid environment; or the membrane may be coated upon the surface of a reference electrode.

Abstract: An optical trap for laser cooling and trapping atoms. Three pairs of laser beams are directed to cross in a vacuum chamber at a common intersection volume, wherein each pair is formed by two counterpropagating beams. Rather than having a mutually orthogonal arrangement in which each beam pair forms an angle χ of 45° to a reference axis, z, these angles are instead between 5°≤χ≤40°. Moreover, in each beam pair, the counterpropagating beams are not precisely aligned in a common path, as in a conventional magneto-optical trap, but are slightly misaligned by respective misalignment angles [α, β, κ] of typically 0.1° to 2°. The misalignment angles and beam widths are however selected so that a common intersection volume for all six beams is maintained. This provides an all-optical trap in which laser cooling and trapping of atoms takes place without a magnetic field being present.

Abstract: An optical fiber has corrugations on an outer surface to dissipate a portion of an input light beam, allowing the remaining portion of the light beam to be coupled to the optical fiber. By dissipating the portion of input light, damage to the optical fiber by uncoupled light is reduced.

Abstract: A computer-implemented method comprises generating computer executable code as one or more code portions; detecting a number of processing operations required to reach one or more predetermined stages in execution of each code portion; and associating with each code portion one or more progress indicators, each representing a respective execution stage of the one or more predetermined stages within execution of that code portion. The code portions are executed by a processor powered by an unpredictable power source. When the processor detects an energy condition indicating that no more than a reserve quantity of electrical energy is available, the progress indicators are used to determine whether or not to perform a checkpoint.

Abstract: A nested anti-resonant nodeless hollow core fiber (NANF) enables transmission of multi-kilowatt, continuous wave (CW) light beams operating in wavelengths between 1050 nm and 1100 nm provided by single mode lasers. Such a NANF has little loss over kilometer ranges, and can be employed in long distance subsurface applications, such as in the petroleum industry.

Abstract: A method of manufacturing a photonic chip. The method comprises providing a wafer comprising a silicon substrate, and a low refractive index layer above the silicon substrate, forming a first trench having a first height and a second trench having a second height by etching the low refractive index layer. The second height is greater than the first height and the second trench has a bottom surface that is closer to the substrate than a bottom surface of the first trench.
