A comprehensive numerical model of dielectric apertured VCSEL is presented,which includes all major physics process in device.Especially the light field is described through vectorial electromagnetic equations.This approach is close to the real situation of modes in active layer and obtains higher accuracy.Furthermore the vectorial field equations are combined with transfer matrix method and time domain finite difference method separately,which can acquire the distribution of light in device and much other information about light propagation process.It is noticed that solutions are more reasonable than those calculated through scalar field equations.This work is helpful to optimize the structure of VCSEL.
