Dissipative solitons have long demonstrated their potential for information processing applications. Because of their compactness and extensive use in the information and telecommunication industry, the case of solitons observed in Vertical Cavity Surface Emitting Lasers (VCSEL) is particularly interesting. Different types of transverse localized states have been observed in a number of different configurations. Here we review the latest results on the existence and dynamics of dissipative solitons in lasers with frequency selective feedback.
