We are concerned with two dimensional localized objects in the transverse plane of an optical cavity. Generally speaking they are named cavity solitons and they can take the form of vortices or bright or dark dissipative spatial solitons. A visualization of vectorial localized structures can be given in terms of isolated zeroes or peaks of either of the two independent polarization components of the electric field. Situations of hole-hole, peak-hole or peak-peak in a given polarization background can be envisaged. A proper classification of these objects depends on the reference states preferred by a particular system. We consider here three different systems which give relevant examples of possible vectorial localized structures and of their dynamics: Broad Area Lasers, Vectorial self-defocusing Kerr Resonators and Type II Degenerate Optical Parametric Oscillator.
