然而,由于受理论计算和图象显示技术等因素的限制,目前的电磁学教材中,通常只能给出平面分布的点电荷系或具有较强对称性、忽略边界效应的带电体的电力线和等势线的二维平面图,这给静电场分布的感性认识带来了一定不便。 - The main work can be summed up as follows : firstly , we studied the thermal - field properties of vcsels , and analyzed the influences of current spreading , material parameters and operating conditions on the temperature distributions . secondly , we began with the electrode voltage and calculated the equipotential s distributions , compared the distributions of voltages and current densities in different depths of vcsels , and then studied the influences of the oxide - confining region with different position or thickness , and the different sizes of the gain - guided aperture and emitting window on the distributions of the injected current density , carrier concentration and temperature in the active region . thirdly , we realized the coupling of electricity , optical and thermal - fields , worked out the threshold voltage , calculated the distributions of the injected current density , carrier concentration and temperature under different offset voltages , and analyzed the impacts of temperature profile and carrier density on the refractive index , fermi levels and optical - field
