摘要： 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.

摘要： A method of making a microfluidic device (200, 201, 300) can include depositing a layer of photoresist onto a first substrate (210, 270, 310), selectively removing the photoresist to expose portions of the first substrate (210, 270, 310), etching the exposed portions of the first substrate (210, 270, 310) to form an array of nano-wells (240, 340), coating each nano-well (240, 340) with metal oxide, and coating the metal oxide on each nano-well (240, 340) with a first material to increase binding of DNA, proteins, and polynucleotides to the metal oxide. A layer of a second material can be deposited on interstitial areas between the nano-wells (240, 340) to inhibit binding of DNA, proteins, and polynucleotides to the interstitial areas. A second substrate (220, 320) can be bonded to the first substrate (210, 270, 310) to enclose the array of nano-wells (240, 340) in a cavity.

摘要： A hollow-core optical fiber may include a hollow core extending along a central longitudinal axis of the fiber; a substrate; a plurality of first cladding elements spaced apart from each other and positioned between the hollow core and the substrate, each of the first cladding elements extending in a direction parallel to the central longitudinal axis of the fiber, each of the first cladding elements including a first capillary; and a plurality of second cladding elements spaced apart from each other and positioned between the hollow core and the substrate, each of the second cladding elements extending in a direction parallel to the central longitudinal axis of the fiber, each of the second cladding elements including a second capillary. Each of the first cladding elements directly contacts the inner surface of the substrate, and none of the second cladding elements directly contacts the inner surface of the substrate.

摘要： An optical ring resonator that includes a closed loop core, a cladding layer, and one or more bus waveguides. The closed loop core is disposed in the cladding layer and is As2Se3 glass. The one or more bus waveguides are disposed in the cladding layer and are optically coupled to the closed loop core. The closed loop core has a zero-dispersion wavelength within a telecommunication wavelength band. The closed loop core has a plurality of resonant modes, including a zero-dispersion resonant mode corresponding with the zero-dispersion wavelength and a plurality of paired resonant modes. Further, the closed loop core has a phase matching bandwidth extending greater than ±40 nm from the zero-dispersion wavelength.

摘要： 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.
