Abstract

It is well known that complex rate equations and the couple wave equation have to be solved by the method of iteration in the simulation of multi-quantum well (MQW) distributed feedback Bragg (DFB) lasers, and a long CPU time is needed. In this paper, from the oscillation condition of lasers, we propose a simple and fast model for optimization of In_1-x-yGa_yAl_xAs strained MQW DFB lasers. The well number and the cavity length of 1.55 μm wavelength In_1-x-yGa_yAl_xAs MQW DFB lasers are optimized using the model. As a result, the simple model gives almost the same results as the complex one, but 90% CPU time can be saved. In addition, a low threshold, high maximum operating temperature of 550-560 K, and high relaxation oscillation frequency of over 30 GHz MQW DFB laser is presented.
