Abstract
We analyze the dynamical behavior of multimode VCSELs with elliptical oxide aperture. An advanced electromagnetic solver is employed to determine the electric field modal thresholds and emission frequencies, while mode competition is simulated with a time-domain mode expansion approach that accounts for coherent effects and carrier-photon spatial coupling. Preliminary performance analysis with NRZ PRBS shows an increase in the modulation bandwidth with respect to the single mode case, allowing for bitrates up to 70 Gbit/s.
