摘要
研究了InGaAs/GaAs/InGaP量子阱激光器在不同温度下的电流-电压特性,并建立了一个理论模型进行描述。实验所用激光器腔长为0.3 mm,脊条宽度为3μm。实验测量得到该激光器在15~100 K的电压温度系数(d V/d T)为7.87~8.32 mV/K,在100~300 K的电压温度系数为2.93~3.17 mV/K。由理论模型计算得到该激光器在15~100 K的电压温度系数为2.56~2.75 mV/K,在100~300 K的电压温度系数为3.91~4.15 mV/K。在100~300 K,实验测量与理论模型计算得出的电压温度系数接近,理论模型能较好地模拟激光器的温度电压特性;但在15~100 K相差较大,还需要进一步完善。
The current-voltage characteristics of an InGaAs/GaAs/InGaP quantum well laser at different temperatures have been investigated.A theoretical model has been developed to simulate the current-voltage characteristics of the laser.The length of the laser cavity utilized in the experiment is 0.3 mm,and the ridge width of the laser is 3μm.Experimental voltage-temperature coefficients(dV/dT)of the laser are from 7.87 to 8.32 mV/K within 15-100 K,and are from 2.93 to 3.17 mV/K within 100-300 K.Theoretical voltage-temperature coefficients of the laser in the range of 15-100 K are 2.56 to 2.75 mV/K,and in the range of 100-300 K are 3.91 to 4.15 mV/K.Within 100-300 K,the theoretical voltage-temperature coefficients are close to the experimental coefficients.However,within 15-100 K,there are large differences between the theoretical coefficients and experimental ones,which need to be improved.
