Paper Abstract

Modeling of a hybrid semiconductor external-cavity laser with an intra-cavity saturable absorber is presented. In this paper the simulations are based on a modified transmission line laser model for an external fiber grating laser. The designed model of a DFECL takes into account time-domain evolution of the dynamic grating due to the standing wave in the external cavity and high-power bleaching of the doped-fiber absorption. In contrast to the previous models of such a hybrid laser, here the properties of the dynamic grating strongly depend on the internal power inside the cavity, which causes the absorption bleaching. Modeling results of lasers at 980 nm and 1490 nm are presented.
