Abstract :
Distributed feedback (DFB) semiconductor lasers are essential devices for high-bit-rate and coherent optical fiber communication systems. The authors derive a new transfer matrix based on two-dimensional theory. They use this new transfer matrix to analyze the X/4 phase shift DFB semiconductor lasers. The linewidth is calculated. The results show that the linewidth calculated by two-dimensional theory is larger than one-dimensional results, this is due to the transverse effects of semiconductors.<>
