Abstract
We analytically and numerically demonstrate that multiwavelength conversion can be realized in a high- photonic crystal nanocavity. With the help of a dynamic-phase-shift effect induced by bandgap-multireflection, the wavelength conversion efficiency of nearly 100% is achieved for a broad conversion range over several hundreds of nanometers, which is much larger than the reported results obtained by other linear methods (e.g., adiabatic wavelength conversion). This approach may open a way for the study of on-chip ultralow-power optical communications and quantum information processing.
