We present a sophisticated large signal dynamic model of index guided VCSELs. The three dimensional waveguide problem is reduced to one dimension by using the effective index method and scattering matrix method. The variation of injection current distribution, refractive index profile, carrier diffusion and spatial hole burning as well as gain spectrum inside the active region are taken into consideration. In addition, the frequency dependence of Bragg reflectors and the longitudinal variation of photon density are also included in our investigation. The dynamic response of VCSELs is calculated by solving the corresponding wave equations and rate equation of carrier concentration in a self-consistent manner. Using this model the dynamic behavior of transverse modes are analyzed.
