Aligned 2-Photon Grayscale Lithography for Free Space Microoptical Coupling in Photonic Packaging

Two-photon grayscale lithography (2GL) enables high-resolution, three-dimensional micro-optics with continuous surface profiles for advanced photonic integration. This talk presents Aligned 2-photon Lithography (A2PL) approaches for wafer-level fabrication of free-space micro-optical elements, supporting efficient optical coupling, beam shaping, and scalable photonic packaging for next-generation integrated photonic systems.
