Abstract: A method of manufacturing a hollow core optical fiber, the method including positioning at least one glass tube in a glass outer cladding to form a preform precursor, the glass tube comprising a first open end and a second open end, and forming a preform from the preform precursor. The method further including drawing the preform into a hollow core optical fiber and, while drawing the preform, thermally treating the preform to manipulate gas pressure within the glass tube by at least one of (i) heating at least a portion of the preform to increase gas pressure within the glass tube and (ii) cooling at least a portion of the preform to decrease gas pressure within the glass tube.

Abstract: A fiber coupler (135) for coupling a plurality of cores (160) of a multi-core optical fiber (105) to an integrated photonic device comprises a grating array comprising a plurality of polarization splitting gratings (180) arranged in a manner that corresponds to the plurality of cores (160) in the multi-core optical fiber (105). The fiber coupler (135) also comprises first and second mode converters (235, 240) extending from first and second sides of each of the plurality of polarization splitting gratings (180) to receive first and second polarization modes of the optical signal scattered by the polarization splitting grating (180). A plurality of waveguides (145-a, 145-b) extends from ends of each of the mode converters (235, 240) to guide a single polarization mode of one of the optical signals.

Abstract: Systems, devices, and techniques for performing wavelength division multiplexing or demultiplexing using one or more metamaterials in an optical communications systems are described. An optical device may be configured to shift one or more phase profiles of an optical signal using one or more stages of metamaterials to multiplex or demultiplex wavelengths of optical signals. The optical device may be an example of a stacked design with two or more stages of metamaterials stacked on top of one another. The optical device may be an example of a folded design that reflects optical signals between different stages of metamaterials.

Abstract: A composite includes a substrate and a target material, wherein the target material includes indium oxide (In2O3), tin oxide (SnO2), and gallium oxide (Ga2O3), and a method for making the same. The method includes positioning the substrate and a target in a chamber and applying radio frequency (RF) power to the chamber to sputter ions of target material from the target onto the substrate.
