ALIGNMENT OF PHOTONIC SYSTEM COMPONENTS USING A REFERENCE SURFACE
20230114532 · 2023-04-13 · ·

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.
