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
具體工作可以概括如下：首先，研究了vcsel的熱場特性，分析了電流擴展，材料參數和工作條件對于溫度分佈的影響；其次，從電極電壓入手，計算出激光器中的等勢線分佈，並對不同深度處的電壓和電流分佈進行比較，研究了高阻區的不同位置和不同厚度、限制層和出射窗口半徑的大小對電流密度、載流子濃度和溫度分佈的影響；再次，實現了電、光、熱耦合，求出了閾值電壓，計算了不同偏置電壓下的電流密度分佈、載流子濃度分佈和熱場分佈，分析了溫度和載流子濃度變化對折射率、費米能級和光場的影響；最後，給出了考慮n - dbr和雙氧化限制層時激光器中的等勢線分佈，分析了n - dbr和雙氧化限制層對vcsel電流密度、載流子濃度、溫度和光場分佈的影響。These methods are following : ( 1 ) in order to build fem model conveniently and enhance calculating speed, interceped a finite length and built a 2d - symmetry model. ( 2 ) in order to apply loads conveniently, kept the entrance of cold fluid. ( 3 ) in order to obtain numerical results in steady situation, lengthened export and import ends
這些方法主要有： （ 1 ）為了便於建立模型並提高計算速度，對于實際工程中採用的長徑比特別大的換熱管採取截取有限長度的方法並建立二維對稱簡化模型； （ 2 ）提出採取保留冷流體入口端，截取有限長度的方法施加載荷； （ 3 ）適當延長翅片管的出口端和入口端，以便獲得穩定工況的數值解。
