摘　　要：超辐射发光管(SLD)的温度稳定性是通过芯片制作、耦合封装和应用控制三个环节实现控制在一定的驱动电流下,通过提高耦合效率、改善温控器件的几何参数以及器件整体的热分布参数,实现SLD大功率、宽光谱的光功率输出,出纤光功率达到750μW/100mA,光谱宽度大于40nm工作温度范围为-40～+70℃,功率波动小于2%The temperature stability of the Superluminescent Diode (SLD) is controlled during three stages: fabricating the chip, fiber coupling and application. Through increasing the coupling ratio, modifying the temperature sensor geometrical parameters and optimizing thermometric parameters of the inner device, the high output power and wide spectrum of SLD are achieved. The data concerning output power is 750 μW/100 mA and the BFWT is better than 40 nm . The working temperature range is from -40 to +70℃ with the output power variance less than 2%.
