Delay feedback induces a spontaneous motion of two-dimensional localized patterns in driven semiconductor microcavities

We investigate the effect of a regular delayed feedback on the mobility properties of 2D localized patterns in a broad area vertical-cavity surface-emitting Laser. We show that the delayed feedback induces a spontaneous motion of two-dimensional localized patterns in an arbitrary direction in the transverse plane. We characterize moving localized patterns by estimating their threshold and calculating their velocity. Finally, we discuss the effects of the phase and the carrier decay rate on the stability of localized patterns.
