Abstract

Quantum cascade laser(QCL) is a new type of semiconductor laser. It has many advantages such as small volume, low threshold, wide working band. Quantum cascade laser can be used in many fields such as atmospheric pollution monitoring, infrared communication, medical diagnosis without injury. Quantum cascade laser produces a large amount of heat, it will greatly influence the performance of the device. We used the finite element analysis software ANSYS to simulate the distribution of temperature field in different packaging materials. The results showed that the InGaAs/InAlAs QCL using In solder packaged device had the best thermal characteristics. Then the InGaAs/InAlAs QCL was fabricated with In solder. And its optical properties were tested. The output power of QCL was 18mW.
