Abstract

One of the most efficient device producing coherent high power radiation in terahertz range in electromagnetic spectrum is Quantum Cascade Laser (QCL). During over a decade of history, together with intensive development of terahertz quantum cascade lasers, respecting simulation software tools has been developed too. The process of development of simulation software is a sophisticated task, because many fields of science meet there-quantum electronics, computing technologies, software development etc. The progress in computing power have made simulation tools much more handy, as calculations of non-complex quantum well heterostructures can be run on a personal computer during a considerable time. Simulation of Quantum Cascade Lasers with complex structures can still be very time-consuming. In this paper few strategies on how to improve and optimize QWWAD software tools are analysed, implemented and corresponding results presented. Improvement of eigenvalue problem solution gave 20 times faster algorithm in solving Schrödinger equation. Other ideas did not give remarkable success.
