Abstract :
In this paper, we present a joint theoretical and experimental investigation on the effect of frequency-filtered and spatially shaped feedback on the emission of a multi-transverse mode VCSEL. We have built for this purpose a delay-differential model which associates a cold-cavity mode expansion to the spin-flip formalism, thereby permitting to track simultaneously the modal and the polarization dynamics of the laser.
