A novel double-Brillouin-frequency spaced multi-wavelength Brillouin erbium-doped fiber laser based on non-linear amplified fiber loop mirror

Abstract

In the paper, a ring double-Brillouin-frequency spaced multi-wavelength Brillouin erbium-doped fiber laser based on non-linear amplified fiber loop mirror filter is demonstrated, in which the non-linear amplified fiber loop mirror (AFLMF) is used as a filter. At the 980nm pump power of 10.29dBm, the tunable laser source center wavelength of 1563nm and power of −3dBm, up to 12 even output channels with 0.16nm spacing are achieved. At the same time, we study the influence of 980nm pump power, the polarization controller and the tunable laser source center wavelength on the number of Stokes light wave.
