We show that an intrinsic symmetry break exists due to geometrical asymmetry of the device structure and that the frequency separation between different modes allows the evaluation of the asymmetry factor. The space-time behavior shows the appearance of higher-order modes coexisting or alternating in time. The dynamical behavior shows a chirping infrequency.born digitalarticleseng©1998 Elsevier Science B. V.Copyright and other restrictions may apply.
