Imaging-system-aware color routers optimized for imaging information
Hyoseok Park, Sehyeon Park, Myungjae Lee +1
Conventional nanophotonic color routers are typically optimized under idealized, normal plane waves. However, this standard assumption fails in real-world imaging-system environmen…

Information-optimized color metalenses for camera imaging
Hyoseok Park, Yeonsang Park
A metalens is conventionally built by prescribing a target phase and matching each meta-atom to it, and making that phase achromatic across the visible band is the main difficulty…

PRISM: Breaking the O(n) Memory Wall in Long-Context LLM Inference via O(1) Photonic Block Selection
Hyoseok Park, Yeonsang Park
Long-context LLM inference is bottlenecked not by compute but by the O(n) memory bandwidth cost of scanning the KV cache at every decode step -- a wall that no amount of arithmetic…
