Cavity solitons are localized intensity peaks that can form in a homogeneous background of radiation. They are generated by shining laser pulses into optical cavities that contain a nonlinear medium driven by a coherent field (holding beam). The ability to switch cavity solitons on and off and to control their location and motion by applying laser pulses(More)
Due to current crowding, the laser emission in medium size VCSELs starts at threshold in a linearly polarized “flower mode” concentrated at the laser aperture periphery. Introducing a holding beam with orthogonal liner polarization we observe localized structure in the center of the device in the orthogonal polarization while the VCSEL keeps(More)
