摘要

This paper presents a numerical procedure for the accurate optimization of a three phase-shift (3PS) distributed feedback (DFB) laser structure. The optimization regards the main figures of merit concerning the laser single longitudinal mode operation: the normalized mode selectivity (S) and the flatness (F). The normalized threshold gain (α_(th) L) is also assessed. A step-by-step description of the numerical method, based in matrix techniques, is performed. S = 0.78 and F = 0.010, with α_(th) L = 1.18 are achieved for the optimized 3PS-DFB laser structure, which strongly improves the performances reported elsewhere relative to optima designs for similar structures. Besides, those results are highly competitive in comparison with the ones achieved with the popular quarterly wavelength-shifted DFB laser structure.
