Abstract :
A closed-form nonlinear model of the distributed feedback (DFB) laser accounting for all of its distortion mechanisms is presented. The laser´s nonlinearity is analyzed by combining Volterra models of the laser´s driving circuit and pn heterojunction nonlinearity with rate equation based models of the active region nonlinearities. The prediction of the model is then compared to distortion measurements.<>
