Based on a two-level rate-equation approach a numerical model is presented here to analyze the external-cavity (EC) quantum cascade lasers (QCLs). Using the presented model, the static and dynamic characteristics of an EC-QCL are computed and analyzed. Simulated results show that due to the longer photon-lifetime in the EC (compared to the internal-cavity), the external emission mode dominates on the internal mode. Additionally, the laser wavelength can be tuned by the change of photon lifetime in the EC, which are determined by the physical length of EC. Transient results obtained from this work are in agreement with experiment data reported earlier.
Keywords: External Cavity, Quantum Cascade Laser, Rate equations, Wavelength tenability.
