Explores optical structural similarity to enhance color routing in CMOS image sensors, suggesting improved integration.
The cover depicts colored beams incident on a CMOS image sensor over a broad range of angles. Distinct angle-specific color routers form a full-sensor-plane array, while an optical structural similarity (OSS) constraint in inverse design suppresses stitching errors between neighboring routers and enables seamless integration across the entire sensor plane without compromising efficient color routing. More details can be found in the Research Article by Haejun Chung and co-workers (DOI: 10.1002/nap2.70220).
