Relationship between Performance of a 1.3μm Double Heterojunction Super-Luminescent Diode and Its Operation Current and Temperature
1．3μmDH-SLD的性能与工作电流和温度的关系

The output optical power, spectra and extinction ratio of a buried double hetero-junction type Super-Luminescent Diode (DH-SLD) module were entirely measured and analyzed when it was operated with different operation current at different temperatures. The measurement results have shown that as a soft threshold device, the SLD' output optical power increases with the operation current and decreases with temperature. Its peak wavelength decreases with the operation current lower than about 110mA. However, the peak wavelength increases with the operation current higher than about 110mA at the same temperature. The peak wavelength increases with the rising of temperature at the same operation current. The 3dB bandwidth decreases with the operation current at the same temperature and increases with temperature at the same operation current . The extinction ratio changes with the operation current and temperature.
