Abstract: A method for producing a hollow-core preform may include rolling a glass sheet to form a rolled-glass structure; and attaching one or more of the rolled-glass structures to an inner surface of an annular support structure to form a hollow-core preform, wherein the inner surface of the annular support structure defines an interior cavity and the one or more of the rolled-glass structures are positioned within the interior cavity. The hollow-core preform may be drawn into a hollow-core optical fiber.

Abstract: A multicore optical fiber that includes a plurality of waveguiding cores disposed in a cladding. The plurality of waveguiding cores include one or more first waveguiding cores that have a first propagation constant and one or more second waveguiding cores that have a second propagation constant, where the first propagation constant differs from the second propagation constant. The one or more first waveguiding cores and the one or more second waveguiding cores are disposed in the cladding in a ring distribution and at least a portion of the ring distribution is arranged based on a quasi-periodic sequence having a plurality of sequence segments. Each sequence segment is determined based on a quasi-periodic function, has an order, and corresponds to an arrangement segment of a first waveguiding cores, a second waveguiding cores, or combinations thereof. The ring distribution includes at least one arrangement segment corresponding with a third-order sequence segment or higher of the quasi-periodic sequence.

Abstract: A hollow-core optical fiber including from 5 to 8 spaced apart cladding elements defining a hollow-core region, each including (a) a first capillary and (b) a second capillary disposed within the first capillary. For each of the cladding elements, (i) the second capillary is offset from the first capillary by an angle within a range of from 20 degrees to 120 degrees and (ii) a ratio of an outer diameter of the second capillary to an outer diameter of the first capillary is within a range of from 0.47 to 0.85. The hollow-core optical fiber exhibits confinement loss of less than 0.056 dB/km for electromagnetic radiation of 850 nm, less than 0.028 dB/km for electromagnetic radiation of 1310 nm, less than 0.204 dB/km for electromagnetic radiation of 1550 nm, and less than 0.016 dB/km for electromagnetic radiation of 2400 nm.

Abstract: A waveguide comprising: a tapered-width first waveguide portion and second waveguide portions and a third waveguide portion, such that along a first direction, widths of a first and the second waveguide portions gradually increase towards a first end of the third waveguide portion, and a distance, in a second direction, between the first waveguide portion and the second waveguide portion gradually decreases from a second end of the first waveguide portion to the first end of the first waveguide portion, wherein the second direction is perpendicular to the first direction; and the maximum distance Gmax between the second end of the first waveguide portion and a second end of the second waveguide portion is greater than 0.2 μm and less than 0.48 μm; and the waveguide has a refractive index between 2 and 4 at a 1550 nm wavelength.

Abstract: A method of making a spot size converter comprising a multi-tip waveguide comprising a first and a second waveguide portions, the method comprising the steps of: coating a multilayer wafer comprising a waveguide material layer with a resist material; exposing the coated resist material to a deep UV beam or an electron beam; developing resist material to form an partial waveguide pattern within the resist material; transferring the partial waveguide pattern to the waveguide material layer, forming an initial waveguide; placing a second layer of resist material over the initial waveguide; patterning a tapered gap region shape in the second layer of resist material by exposing the second layer of resist material to a deep UV beam or an electron beam; and transferring the tapered gap region shape to the waveguide material layer of the initial waveguide to form a tapered gap region inside the initial waveguide.

Abstract: A multicore optical fiber that includes a plurality of waveguiding cores disposed in a cladding. The plurality of cores are situated adjacent to at least one other core with a core center to core center spacing being not larger than 10 times the radius of the average core, such that the greater than 10% of the light will couple from one core to the adjacent core over a propagating distance of 1 cm, along the fiber length so as to provide coupling between the adjacent cores and to enable quantum walk. The plurality waveguiding cores are disposed in the cladding in a ring distribution or at least a portion of the ring distribution.

Abstract: A waveguide array that includes a plurality of waveguides disposed in a substrate. The plurality of waveguides include one or more first waveguides that have a first propagation constant and one or more second waveguides that have a second propagation constant, where the first propagation constant differs from the second propagation constant. The one or more first waveguides and the one or more second waveguides are disposed in the substrate in a linear distribution and at least a portion of the linear distribution is arranged based on a quasi-periodic sequence having a plurality of sequence segments. Each sequence segment is determined based on a quasi-periodic function, has an order, and corresponds to an arrangement segment of a first waveguide, a second waveguide, or combinations thereof. The linear distribution includes at least one arrangement segment corresponding with a third-order sequence segment or higher of the quasi-periodic sequence.
