Symmetry breaking and motion of Bloch Cavity Solitons

Bloch Cavity Solitons (BCS) are stable localized solutions existing in nonlinear cavities with the refractive index modulated in both longitudinal and transverse directions. Employing periodic photonic structures for the effective tailoring of net diffraction, one can design the shape and even the existence domain of BCSs. In this contribution we study mobility properties of BCSs. In particular we report on an effective control of location and velocity of the BCS by means of the excitation of dispersive linear waves which are resonant with the BCS. Because of the large group velocity these dispersive waves propagate across the cavity over large distances. In the second part we show that BCSs can undergo spontaneous symmetry breaking resulting in spontaneous motion of BCSs even without any additional control beam.
