Influence of dispersion of fiber Bragg grating mirrors on formation of optical power spectrum in Raman fiber lasers

摘要

We show, from experiments and numerical simulations, that dispersion of fiber Bragg grating (FBG) mirrors influencesnthe formation of the optical power spectrum of Raman fiber lasers by shifting the cavity zero-dispersionnwavelength inside the FBG reflectivity bandwidth. This results in a spectrum asymmetry, which is well describednfrom a master equation including a third-order dispersion term.
