“…The output of the linear-cavity BEFL was taken at the output port of the first circulator (Cir1) and appears at a Brillouin frequency that shifted from that of an injected BP. It is worth noting that only a common EDF coil was used in this experiment to amplify the Stokes signal and support multiple-wavelength operation, as compared to the utilization of two EDF coils in [7,8]. Furthermore, only a single 980-nm pump laser was deployed instead of two units of pump laser, as discussed in [7,8].…”

This design shows its simplicity with the reduced number of optical components used to create a multiwavelength laser.…”

“…This hybrid technique led to the development of multiwavelength BEFLs by feeding back the Brillouin Stokes into the cavity via the nonresonant direction [5,6]. The enhanced version of the ring-cavity BEFL, incorporating an internal active feedback, was demonstrated in [7,8].…”

a b s t r a c tWe experimentally demonstrate a multiwavelength Brillouin-erbium fiber laser in two configurations; uni-directional and bi-directional propagation of Brillouin pump and Brillouin Stokes signals through an Erbium-doped fiber gain. The influence of these configurations on the performance of the output parameters in terms of lasing threshold, output channel generation and tuning range of the generated output channels are investigated. We discovered that there is a trade-off between these two fiber laser configurations. The uni-directional amplifier configuration provides greater tuning range of 46.8 nm against 23 nm at maximum Brillouin pump power of 2 mW and 1480-nm pump power of 130 mW. On the other hand, the bi-directional amplifier configuration provides 13 output channels against 6 output channels obtained from the uni-directional amplifier configuration at the same pumping powers. Nevertheless, the bi-directional amplifier configuration requires much lower pump power to initiate lasing.

“…Previous works by several authors [3][4][5][6][7] on BEFL configurations require an external Brillouin pump (BP) signal to initiate Brillouin gain in SMF. In this paper, a new BEFL scheme is demonstrated using a self-excited BP.…”
