Waveguide modulated photonic molecules with metallic confinement

Photonic molecules based on the evanescent wave have been displayed unique physical characteristics, such as quality factor enhancement of optical system and mode transition between different order modes etc. Waveguide, as basic photonic element, is introduced for indirect optical interaction and guided emission of photonics molecules. Due to that the metal can effectively confine the photons in a fixed space and facilitates the high density device package as optical insulator, the optical characteristics of photonic molecules with metallic confinement, including the mode and emission characteristics, are investigated by electromagnetic analysis, combined with finite difference time domain simulations. The results show the metal dissipation of odd and even state split since they have different morphologies at coupling area and the guided emission is strongly determined by the metal-dielectric confined waveguide. Moreover, non-local optical interaction between two whispering gallery circular resonators through a waveguide coupled in radial direction is proposed for breaking the small depth of evanescent permeation. Strong optical interaction is found from the even state and interaction intensity is relative to the features of waveguide.
