Abstract :
We demonstrate symmetry breaking in a multistable system composed of three coupled nonlinear cavities. Using positive pulses it is possible to switch between the asymmetric states, thus resulting in tristable flip-flop behaviour. Coupled-mode theory gives analytical results and precise insight into the intricate dynamical behaviour.
