We numerically investigate the interaction dynamics of coupled cavities in planar photonic crystal slabs in different configurations. The single cavity is optimized for a long lifetime of the fundamental mode, reaching a Q-factor of ≈43, 000 using the method of gentle confinement. For pairs of cavities we consider several configurations and present a setup with strongest coupling observable as a line splitting of about 30 nm. Based on this configuration, setups with three cavities are investigated.
► Numerical study of strongly interacting planar photonic crystal cavities. ► Optimization of Q factor to 43,000 for single cavity. ► For two pair of cavities strongest coupling is found for an angle of 30°. ► For three cavities a linear arrangement is optimal.
