    Abstract: Structures and methods for passively aligning a photonic die with a receiving substrate are described. Three alignment surfaces, having dimensions greater than a desired alignment accuracy, may be formed on the photonic die and used to passively and accurately align the photonic die to a receiving substrate in six degrees of freedom. Two of the three alignment surfaces on the photonic die may be formed in a single mask-and-etch process, while the third alignment surface may require no patterning or etching. Three complementary alignment surfaces on the receiving substrate may be formed in a single mask-and-etch process.

    Abstract: A photonic device comprising a first waveguide core and a second waveguide core. The first waveguide core is asymmetric relative to an imaginary plane that bisects a height of the first waveguide core and is parallel to the bottom surface of the first waveguide core throughout a first region of the photonic device. A side surface of the second waveguide core is parallel to the first waveguide core throughout the first region of the photonic device.
