“…S TIMULATED Brillouin scattering (SBS) with narrow band and low noise has broad applications in frequency shifter [1], microwave frequency generation [2], [3], narrow bandwidth low-noise amplification [4], [5] and fiber laser [6]- [12]. Meanwhile, extra attention has been attracted to single longitudinal mode Brillouin fiber laser (BFL) with high quality, low loss and cost.…”

A novel single longitudinal mode (SLM) Brillouin fiber laser (BFL) with cascaded ring (CR) Fabry-Pérot resonator is proposed and demonstrated. By optimizing the CR length of the single mode fiber cavity at 100 m (or 50 m) and 10 m, stable SLM operation is obtained. Therefore, the threshold power is lower and linewidth is narrower than that of previously reported BFL with 10 m (or 20 m) single cavity. Additionally, there is no additional attenuation except intrinsic loss of optical devices. The measured linewidth with 60 dB (or 45 dB) improved value of side mode suppression ratio is 0.41 kHz (or 3.23 kHz), which is three (or two) orders of magnitude than that of the pump. Using a stabilizing feedback loop based on autotracking technique with polarization maintaining fiber-based optical delay line, the SLM BFL exhibits good performance with 6% power fluctuation in 1 h. Index Terms-Cascaded ring Fabry-Pérot resonator, Brillouin fiber laser (BFL), single longitudinal mode (SLM), narrow linewidth.

“…The input power at the PD is 1 mW. By optimizations of the fiber length shown in [15], one can assume a further decrease of the phase noise. The peaks at 55 and 150 Hz have their origin in the 9.8-GHz signal generator, which provides the MZM with the necessary power.…”

“…In contrast to that, Ferreira et al [15] reported that driving the amplifier in the saturation regime could significantly reduce the SEN. A short amplifier length can provide considerable improvement on the gain of the signals and decreases the SEN as well. Furthermore, the noise power increases with signal detuning.…”

Recommended Citation Junker, M. et al. (2006) Abstract-Measurements of phase noise of a 40-GHz carrier signal are presented. The carrier is generated by the amplification of harmonics due to stimulated Brillouin scattering. An analogy to a generation of millimeter waves by an erbium-doped fiber instead of the Brillouin amplifier is investigated and discussed. In our setup, both show a comparable behavior in respect to their noise characteristics.Index Terms-Brillouin scattering, millimeter-wave generation, phase noise.

“…On the contrary, the use of the BLS is inherently low noise because it relies on the depletion of the pump by a relatively large Stokes wave. This means that the Brillouin amplifier is operating in saturation and thus the spontaneous scattering noise is reduced [19]. Moreover, it has been shown that the noise that couples to the pump wave via depletion is of lower magnitude and has narrower bandwidth than the noise in the Stokes wave [20].…”
