Abstract
We report 10 Gbps all-optical switching using a photonic molecule based on two lattice-shifted coupled photonic crystal nanocavities in Indium Phosphide. The process is enhanced by the asymmetric Fano resonance lineshape leading to 0.4 dB OSNR penalty at error rates smaller than 10−9 with switching energies as low as 19.5 fJ/bit or 39 fJ/pulse.
