Abstract :
In this paper, a general computer code is presented for the analysis of gain coupled (GC)-DFB structures. The code allows to consider and to compare different GC-DFB structures realized with a gain grating (GG) or an absorption grating (AG) or a second order index grating (SOG). The formulation for index grating laser has been extended considering two rate equations for AG lasers. Linewidth, side-mode suppression ratio, FM and AM response and other laser characteristics are evaluated and discussed for different structures
