Analytical model of the Ultrabroadband Operation of Transverse-Coupled-Cavity VCSELs

The ultrabroadband operation of transverse-coupled-cavity vertical-cavity-surface-emitting lasers is investigated in this work. Relying on a closed-form expression of the intensity modulation response, our model allows for an extended and fast parametric campaign of the design inputs, as well as an easy interpretation of the bandwidth enhancement.
