Abstract :
We experimentally show spontaneous breaking of mirror-symmetry in two evanescently coupled photonic crystal nanocavity-lasers. A transition from a delocalized mode, to two spatially localized states, is observed in the form of a pitchfork bifurcation. Coexistence of these states is demonstrated through short pulse excitation.
