Abstract: We present a detailed study of the localized coupled-cavity modes in a photonic molecule formed from two dielectric spherical microcavities with CdTe nanocrystals, which show a multi-peak narrowband modal structure resulting from lifting of the mode degeneracy with respect to the azimuthal quantum number. The waveguiding through the coupled microcavities and wavelength switching effect is demonstrated. The feasibility of photonic molecules as the basis for a multi-channel, wavelength-tunable optical delay device is analysed.
