A reconfigurable multi-channel on-chip photonic filter for programmable optical frequency division. [PDF]

Nanophotonics
Abstract Recent advancements have broadened the application of photon filters based on Bragg gratings within optical communication networks and optical input/output interfaces. Traditional gratings, however, suffer from a fixed refractive index modulation distribution once manufactured, constraining their adaptability and flexibility.
