Modeling of the Quantum Cascade Laser Characteristics

摘要

The mathematical model of the quantum cascade structure was proposed for the characteristics analysis of the laser in the terahertz frequency range. Developed model allows to investigate following parameters and characteristics: oscillation frequency, gain frequency characteristics and threshold current density of the super lattice laser heterostructures. The model can be used for optimizing structure and characteristics of the quantum cascade laser (QCL) by the geometrical and electrical parameters.
