Abstract: Semiconductor lasers for fiber-optic communication are now developing fast along the direction of miniaturization and integration. The integration of laser device generates a lot of heat, and a refrigerator is required to control the temperature. When gold wire is used to power the refrigerator, it must be able to allow a few Amperes of direct current to flow through without fusing. In this case, thermal analysis and fusing experiments of the gold wire are very necessary. In the paper, based on the theoretical analysis of fusing current in gold wire, ANSYS software is used to perform thermal analysis of gold wire and the fusing current of 2.0 mm gold wire is found. The results have direct guiding significance for the development of the cooled laser.
