Abstract:The waveguide‐integrated metasurface introduces a novel photonic chip capable of converting guided modes into free‐space light. This enables functions such as off‐chip beam focusing, steering, and imaging. The challenge lies in achieving hyper‐multiplexing across diverse parameters, including guided‐wave mode type, direction, polarization, and notably, multiple wavelengths. Here, a comprehensive end‐to‐end inverse design framework is introduced, rooted in a physical model, for the multifunctional design of on‐… Show more
