  • Publication number: 20240085629
    Abstract: A method of fabricating a waveguide structure to form a solid-core waveguide from a waveguiding layer may include etching a fluid channel into the waveguiding layer, etching a first air-gap and a second air gap into the waveguiding layer, wherein etching the first and the second air-gaps creates a solid-core waveguide in the waveguiding layer between the first air-gap and the second air-gap. A method for fabricating a waveguide structure to form a solid-core waveguide may include forming a first trench, a second trench, and a third trench in a substrate layer, and depositing a waveguiding layer on the machined substrate layer, wherein depositing the waveguiding layer creates a hollow core of a fluid channel in a location corresponding to the first trench, and a solid-core waveguide portion in the waveguiding layer in a location corresponding to an area between the second trench and the third trench.

  • Publication number: 20230131829
    Abstract: A waveguiding structure (500) includes one or more fluid channels (518) intersected by a waveguide (514). An aperture layer (570) of the waveguide structure includes an array of apertures adjacent to the one or more fluid channels, such that the array of apertures may allow emission signals from analytes in the fluid channels to pass through the aperture layer for detection. The aperture layer may be etched using a first etching step, while an air-gap in a substrate of the waveguiding structure may be etched using a second etching step, wherein the first etching step has a higher level of precision than the second etching step. The array of apertures may comprise one or more one-dimensional signature patterns of apertures associated with specific fluid channels of the device, such that the signature patterns may be used to demultiplex signals and to correlate a signal with one of the plurality of channels.

  • Publication number: 20230114532
    Abstract: Systems and method for aligning components of photonic systems are provided. An optical component for integration into and optical coupling within a photonic system is created by separating the component from a substrate to form a precisely defined surface on the optical component, the surface being precisely spaced from an optical feature of the component to be optically coupled within the photonic system. The precisely defined surface of the optical component is then pressed against a reference surface to position the optical feature in a predefined position and/or orientation for optical coupling of the optical feature within the photonic system. Passive precise alignment and optical coupling is thus provided without the need for iterative readjustment, multi-axis feedback, or active feedback.
