We show numerically that bright and dark cavity solitons can be obtained in bidirectional class A ring lasers only if the phase invariance of the electromagnetic field is broken. The phase invariance symmetry is responsible for the existence of phase waves, which generate long-range interactions destroying the property of independence among otherwise localized structures. We improved the usual model describing such types of lasers, and we prove that it leads to genuine cavity solitons.

  11. The terms “dark” and “bright” solitons may lead to some misunderstandings. In , they refer to a local lack and overload of light, respectively, and are absolutely not related to the usual topological solitons observed in integrable dynamical systems. Also, contrary to the usual “cavity solitons” , the stability of the localized structures in does not result from a balance between bistability and modulational instability. This point is well described in D. Gomila, P. Colet, M. San Miguel, A. J. Scroggie, and G. L. Oppo, IEEE J. Quantum Electron. 39, 238 (2003). [CrossRef]
