Abstract: We present an experimental study of a Vertical-Cavity Surface-Emitting laser with polarized optical feedback. The system displays single-mode Low Frequency Fluctuations (LFF) for a wide range of pump current. Above the solitary laser threshold we observe a new kind of couple-mode dynamics with a leading LFF behavior in one polarization and an induced pulsed emission in the orthogonal one.
