摘要

采用波长漂移法对基于C-mount封装类型的不同尺寸芯片的热阻进行测量

得到了使热阻最小的最佳芯片尺寸和铟焊料厚度。测量结果表明

在铟焊料厚度为10 m、输出功率为2 W、条宽为200 m、腔长为2 000 m时

激光器芯片的热阻最小值为2.01 ℃/W。在铟焊料厚度为5 m和10 m两种条件下

对腔长为2 000 m的不同条宽的激光器芯片的热阻进行了测量

在铟焊料厚度为5 m时

激光器芯片的热阻由原来的2.01 ℃/W降到了1.85 ℃/W。

Abstract

Thermal-resistor of different chips based on C-mount package have been measured with the method of wavelength shift in this paper.Through the thermal-resistance measurement

we can get the best size of chip and the thickness of In solder to make the smallest thermal-resistance. The results show that when the thickness of In solder is 10 m

the output power is 2 W

the bar width is 200 m

the cavity length is 2 000 m and the minimum thermal-resistor of the chip is 2.01 ℃/W.The thermal-resistors with carvity length of 2 000 s have been measured when the In solder thickness is 5 m and 10 m. The results show that the thermal-resistor dropes from 2.01 ℃/W to 1.85 ℃/W for the 5 m In solider.
