The objective of this paper is to summarize the results obtained for the state of polarization in the emission of a vertical-cavity surface-emitting laser with frequency-selective feedback added. We start our research with the single soliton, this situation presents two perpendicular main orientations, connected by a hysteresis loop. In addition, we also find the formation of a ring shaped intensity distribution, the vortex state, that shows two homogeneous states of polarization with very close values to those find in the soliton. For both cases above, the study shows the spatially resolved value of the orientation angle. It's important to remark too the appearance of a non negligible amount of circular light that gives vectorial character to all the different emissions investigated.
