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.
