Phys. Rev. E 66, 036607 (2002) [8 pages]Self-propelled cavity solitons in semiconductor microcavitiesReceived 19 April 2002; published 19 September 2002 We demonstrate the existence of both bright and dark spontaneously moving spatial solitons in a model of a semiconductor microcavity. The motion is caused by temperature-induced changes in the cavity detuning and arises through an instability of the stationary soliton solution above some threshold. An order parameter equation is derived for the moving solitons and is used to explain their behavior in the presence of externally imposed parameter modulations. The existence of two-dimensional moving solitons is demonstrated and an example given of their interaction. © 2002 The American Physical Society URL:
