增益导引雷射 - 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
具体工作可以概括如下：首先，研究了vcsel的热场特性，分析了电流扩展，材料参数和工作条件对于温度分布的影响；其次，从电极电压入手，计算出激光器中的等势线分布，并对不同深度处的电压和电流分布进行比较，研究了高阻区的不同位置和不同厚度、限制层和出射窗口半径的大小对电流密度、载流子浓度和温度分布的影响；再次，实现了电、光、热耦合，求出了阈值电压，计算了不同偏置电压下的电流密度分布、载流子浓度分布和热场分布，分析了温度和载流子浓度变化对折射率、费米能级和光场的影响；最后，给出了考虑n - dbr和双氧化限制层时激光器中的等势线分布，分析了n - dbr和双氧化限制层对vcsel电流密度、载流子浓度、温度和光场分布的影响。
