Super-Strong Photonic Localizations in Symmetric Defect Waveguide-Ring Networks

Super-Strong Photonic Localizations in Symmetric Defect Waveguide-Ring Networks

Super-strong photonic localizations that occur in symmetric defect waveguide-ring networks (SDWRNs) are presented in this study. It is found that the intensity of maximal photonic localization can increase as an exponential function with the number of rings and as a power function with the breaking...
