The synchronization of unidirectionally coupled multi-transverse-mode vertical-cavity surface-emitting lasers (VCSELs) is numerically studied. It is demonstrated that synchronization can be achieved between each transverse mode of a master laser and its counterpart, a slave laser. This result opens the opportunity for multichannel chaotic communications by use of multi-transverse-mode VCSELs. It is further shown that two distinct synchronization regimes exist, complete synchronization and injection locking, which can be distinguished by the lag time between the master and the slave laser intensities.
