“…[4][5][6] However, the SBS in optical fibers has been utilized advantageously in diverse applications, such as Brillouin amplification, [7,8] microwave signal generation, [9] multiwavelength Brillouin fiber lasers (MWBFLs), [10,11] and distributed strain/temperature sensing. [12] Among these applications, MWBFLs have been of great interest for utilization in dense wavelength division multiplexing communication systems because of their narrow linewidth, [13] wide tunable range, [14] and stable operation at room temperature. [15] For silica-based fibers at 1550 nm, the frequency downshift of the Stokes light from the pump light is approximately 10 GHz or 0.08 nm.…”

We demonstrate multiwavelength Brillouin fiber lasers (MWBFLs) with double-frequency spacing based on a small-core fiber (SCF) and a standard single-mode fiber (SMF), which have core diameters of 5 and 8.8 μm, respectively. Experimental results show that the SCF-based MWBFL exhibits a higher laser output power and a lower pump threshold. The output powers of the SCF-based MWBFL are > 1.4 times those of the SMF-based MWBFL. Moreover, the threshold power required to generate each channel of the SCF-based MWBFL is 59% that of the SMF-based MWBFL. When the same pump power of 180 mW is injected, the number of laser channels generated for the SCF-based MWBFL is 13, which is twice that generated for the SMF-based MWBFL. In addition, the SCF-based MWBFL exhibits good wavelength tunability from 1535 to 1565 nm and temporal stability over an hour.

“…However, due to the homogenous line broadening property of EDFs at room temperature, EDF-based multiwavelength fiber lasers have very strong mode competition and unstable multiwavelength outputs. To address this issue, various techniques have been proposed, such as the frequency shifting [13], optical feedback [14][15][16], utilization of the EDF amplifier [17][18][19], nonlinear polarization rotation (NPR) [20][21][22][23] and nonlinear optical loop mirror [24][25][26][27] based methods.…”

All-fiber polarization interference filter based uniform multiwavelength erbium-doped fiber laser

We demonstrate a compact and stable room-temperature multiwavelength erbium doped fiber laser by employing 45° tilted fiber gratings based on an all-fiber polarization interference filter. Benefiting from the filter, the channel number, linewidth, uniformity and stabilization of the multiwavelength laser are greatly improved. The filter also works as a functional polarizing device in a nonlinear polarization rotation, leading to the multiwavelength operation. Instead of a highly nonlinear fiber, the single mode fiber is used to provide enough linearity and to reduce the splice loss. More than 80 wavelengths (within a 3 dB bandwidth), lasing with a linewidth of 0.03 nm and a signal-to-noise ratio of 33 dB, are obtained. The wavelength spacing of 0.164 nm agrees with the channel spacing of the filter, and can be flexibly controlled by adjusting the length of the filter.

“…Various techniques have been investigated for multi-wavelength generation, which are phase modulation [1], nonlinear optical loop mirror [2], [3], four-wave mixing (FWM) [4]- [6], the cascaded stimulated Brillouin scattering(SBS) [7]- [9]. Among these techniques, MWFL based on stimulated Brillouin scattering (SBS) is a hot research pot due to its unique characteristics such as ultra-narrow linewidth [10], the stable multi-wavelength operation at room temperature [11], low threshold power [12], low noise intensity [13], and wide tunable range [14], [15].…”

We demonstrate a triple Brillouin frequency spacing, multi-wavelength Brillouin laser combined with two cavities: a single Brillouin frequency spacing cavity and a double Brillouin frequency spacing cavity. In this simple structure, the optimization of multi-wavelength lasing is done with proper adjustments of Brillouin pump (BP) power and 980-nm pump power. When setting the BP power to 3-dBm and 980-nm pump power to 27.78 dBm, up to ten channels with frequency spacing of 0.26 nm are generated. The output wavelength can be tuned in a wide range of 45 nm, from 1525 to 1570 nm. We also compared and analyzed this scheme under the condition of single linear cavity 1 and double ring cavity 2. The proposed multiwavelength laser has the potential applications in the areas of space optical communication and optical communications and microwave signal source.Index Terms-Brillouin fiber laser, stimulated Brillouin scattering, triple Brillouin frequency shift.
