Temporal Localized Structures in mode-locked Vertical External-Cavity Surface-Emitting Lasers
Temporal Localized States (TLSs) are individually addressable structures
traveling in optical resonators. They can be used as bits of information and to
generate frequency combs with tunable spectral density. We show that a pair of
specially designed nonlinear mirrors, a 1/2 Vertical-Cavity Surface-Emitting
Laser and a Semiconductor Saturable Absorber, coupled in self-imaging
conditions, can lead to the generation of such TLSs. Our results indicate how a
conventional passive mode- locking scheme can be adapted to provide a robust
and simple system emitting TLSs and it paves the way towards the observation of
three dimensions confined states, the so-called light bullets.Comment: submission to Optics Letter
