In this paper, a self-consistent model comprising of rate equation and thermal conduction equation, in which all possible pathways are considered, is used to investigate the influence of the oxide aperture size on output power and modulation bandwidth of 1.3 µm photonic crystal (PhC)-VCSEL. A 3D finite-difference time-domain method has been applied to simulate the mode field distribution of fundamental and high order modes of PhC-VCSEL. The frequency response of PhC-VCSEL has been calculated. The results showed that the high single-mode output power and postponed frequency roll-over position can be achieved with a larger oxide aperture. The highest output power ~ 4.3mW and the maximum modulation bandwidth 1.82 GHz can be achieved by modifying the size of the oxide aperture.
