Abstract

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.
