用数值方法对半导体折射率波导激光器的模式进行了研究．提出了一种方法可以高效并且自洽地求得谐振腔内的模式分布．利用该方法对一种ＧＲＩＮ－ＳＣＨ ＢＨ ＳＱＷ 激光器的波导谐振腔的光子能量相关的模式特性进行了数值计算，分析了阱宽、阱内载流子浓度等因素的影响
The mode of semiconductor refractive index waveguide laser is studied numerically. A method is proposed to obtain the mode distribution in the resonator efficiently and consistently. The photon energy related mode characteristics of a waveguide cavity of a GRIN-SCH BH SQW laser are numerically calculated using this method. The effects of the well width, the carrier concentration in the well and other factors are analyzed
