ABSTRACT

In this paper, when both the refractive index grating and the gain grating exist in a 1.55um DFB laser with two cleaved mirror facets, when the phase of  is fixed to 0 and the phase of is changed to   , , , , the change in frequency and oscillation gain was theoretically analyzed. In the case of    , the oscillation gain required for lasing is the lowest and the most stable frequency operation is obtained in the case of ( phase=,  phase=) and   , when  is varied from 0.1 to 10. In the case of    , when ( phase=,  phase= ) and   , the oscillation gain required for lasing is the lowest and the difference between the oscillation gains of the higher-order modes is large so that the most stable frequency operation is obtained.
