Summary:
We experimentally observe synchronization of chaos in two mutually-coupled vertical-cavity surface-emitting lasers (VCSELs). We observe in-phase and anti-phase synchronization of polarization-resolved chaotic temporal waveforms under the condition of injection locking. We investigate leaderlaggard relationship between two chaotic waveforms of mutually coupled VCSELs and find that the laser with longer wavelength becomes the leader. The leaderlaggard relationship is related to the characteristics of injection locking in optically coupled VCSELs.
