    摘要: In an example, a photonic system includes a Si PIC with a Si substrate, a SiO2 box formed on the Si substrate, a first layer, and a second layer. The first layer is formed above the SiO2 box and includes a SiN waveguide with a coupler portion at a first end and a tapered end opposite the first end. The second layer is formed above the SiO2 box and vertically displaced above or below the first layer. The second layer includes a Si waveguide with a tapered end aligned in two orthogonal directions with the coupler portion of the SiN waveguide such that the tapered end of the Si waveguide overlaps in the two orthogonal directions and is parallel to the coupler portion of the SiN waveguide. The tapered end of the SiN waveguide is configured to be adiabatically coupled to a coupler portion of an interposer waveguide.

    摘要: An optoelectronic assembly may include a photonic integrated circuit (PIC) with a top surface and a laser with a top surface and a bottom surface. The optoelectronic assembly may also include a housing configured to cooperate with the PIC to one or both of house and support one or more components. The housing may include a PIC mount including a first surface to interface with the top surface of the PIC, and a laser mount including a second surface to interface with the top or bottom surface of the laser. The first surface and the second surface may be parallel to each other.

    摘要: In an embodiment, a delay line interferometer (DLI) multiplexer (MUX) includes a first stage and a second stage. The first stage includes a first DLI and a second DLI. The first DLI includes a first left input, a first right input, and a first output and has a free spectral range (FSR) that is about four times a nominal channel spacing. The second DLI includes a second left input, a second right input, and a second output and has an FSR that is about four times the nominal channel spacing. The second stage is coupled to the first stage and includes a third DLI. The third DLI includes a third left input optically coupled to the first output, a third right input optically coupled to the second output, and a third output. An FSR of the third DLI is about two times the nominal channel spacing.

    摘要: In an example, a photonic system and method include a photonic integrated circuit (PIC) including a silicon (Si) waveguide and a first silicon nitride (SiN) waveguide. The system also includes an interposer including a second SiN waveguide including vertical tapers on the second SiN waveguide by increasing a thickness of the second SiN waveguide in a direction toward the first SiN waveguide to allow an adiabatic optical mode transfer and decreasing the thickness of the second SiN waveguide in a direction away from the first SiN waveguide to inhibit the optical mode transfer.
