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