Highly efficient ultra-broad beam silicon nanophotonic antenna based on near-field phase engineering
Abstract Optical antennas are a fundamental element in optical phased arrays (OPA) and free-space optical interconnects. An outstanding challenge in optical antenna design lies in achieving high radiation efficiency, ultra-compact footprint and broad radiation angle simultaneously, as required for d...
