Abstract :
The natural linewidth in DFB lasers is calculated on the basis of a new formula for the line shape which has been derived in the process of applying effective nonlinear photorefractivity which is assumed. Corrugation, phase, and amplitude components of the natural linewidth are taken into account. We have defined and found numerical values of laser parameters describing the natural linewidth of DFB lasers by solving an inverse problem, and then have simulated 12 experimental measurements.
