“…In order to optimize the operation of BEFL in producing a maximum number of Brillouin Stokes lines, three parameters must be carefully adjusted; BP power, BP wavelength and 1480 nm pump power. From the previous work, the number of Brillouin Stokes can be increased by increasing the primary pump into the EDF [1,2]. This is only true if the BEFL operation is within the tuning range whereby the free-running cavity modes are totally suppressed.…”

Abstract:In this paper, a multiwavelength linear-cavity Brillouin-Erbium fiber laser pumped by a 1480 nm pump laser is demonstrated to operate in the L-band region. The issue of low gain efficiency of L-band in Erbium-doped fiber pumped with 980 nm pump lasers is resolved with this pumping scheme. The amount of 1480 nm pump power to produce the first Brillouin Stokes line oscillating in the cavity is 23.4 mW only. The proposed laser configuration has a wide tuning range of 16 nm from 1591 to 1607 nm with six Brillouin Stokes lines within this tuning range. The maximum number of 23 Brillouin Stokes lines with a spacing of 0.089 nm is achieved by setting the Brillouin pump wavelength at 1595.5 nm and its power is set at 3.2 mW. Wavelength, nmOutput spectrum of L-band linear cavity BEFL at BP power of 3.2 mW, BP wavelength of 1595.5 nm and 1480 nm pump power is set to 100 mW

“…It can be seen that the efficient utilization of the EDF and Brillouin gains led to a higher number of generated output channels. Brillouin pump wavelength and power [3][4][5][6]. However, higher injected Brillouin pump power depleted the EDF gain and thus permitted efficient use of the EDF gain on the Stokes signals amplification.…”

This paper presents the characteristics of multiple wavelength L-band Brillouin-erbium comb fiber laser with intra-cavity pre-amplified Brillouin pump power technique at low pumping powers. The issue of EDF gain depletion and Brillouin gain saturation are resolved by the proposed structure. The laser structure achieves a low threshold power and is able to produce high number of output channels at low pumping powers. It produces up to 33 channels at 50 mW and 0.042 mW of 1480 nm pump and Brillouin pump powers, respectively.

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.
