Abstract

By engineering the electromagnetic environment of L3 photonic crystal nanocavities a strong re-direction of the emission pattern is achieved. This is experimentally demonstrated by means of far-field measurements. The same approach is implemented for coupled L3 nanocavities. FDTD simulations show strong beaming effect for both the symmetric and the anti-symmetric modes of the photonic molecule. Laser operation of the single folded cavities is demonstrated, showing that the band-folding procedure implemented here preserves a high Q-factor operation.
