Abstract: 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.

Abstract: In an example, a coupled system includes a first waveguide, at least one second waveguide, and an interposer. The first waveguide has a silicon (Si) core having first refractive index n1 and a tapered end. The at least one second waveguide each has a silicon nitride (SiN) core having a second refractive index n2. The interposer includes a third waveguide having a third refractive index n3 and a coupler portion, where n1>n2>n3. The tapered end of the first waveguide is adiabatically coupled to a coupler portion of one of the at least one second waveguide. A tapered end of one of the at least one second waveguide is adiabatically coupled to the coupler portion of the third waveguide of the interposer. The third waveguide of the interposer has an optical mode size that is similar to the mode size of a standard single mode optical fiber.
