碩士 === 義守大學 === 電機工程學系碩士班 === 97 === In this article, we utilize effective mass approximation method can is it simplify to take energy bands, make a theoretical analysis by first principle of quantum mechanics, hit the most important reference value of the semiconductor laser - Gain, calculate and map with procedure simulation. The next step, we used the finite difference method to evaluate energy levels and wave functions in quantum well to be enable the procedure to expand to the quantum well structure, and getting the gain curve under all kinds of structure of lasers, in order to offer the simulation before the experiment in the future to assess.
