“…In this regime, fluctuations of Stokes η are sharply reduced, and up to 20 dB/Hz reduction compared to the RIN of the input pump laser is experimentally observed. Similar noise fluctuations reduction have been demonstrated in semiconductor optical amplifier (SOA) used in the saturation regime [31,32]. In the following Subsection, we describe in detail the RIN behavior of individual Stokes order for various operating points to show the rich dynamics of RIN when MBL emission takes place.…”

We investigate the Relative Intensity Noise (RIN) properties of a multi-Stokes Brillouin fiber ring laser. We experimentally analyse intensity noise of each Stokes waves and study the noise dynamics of the cascaded Brillouin scattering process. We observe up to 20 dB/Hz intensity noise reduction compared to that of the RIN input pump laser. We examine the impact of the fiber ring quality factor on the laser RIN features such as amplitude reduction and relaxation frequency. A numerical model based on a set of coupled-mode equations replicate the experimental observations; confirming the class B like behavior of a multi-Stokes Brillouin laser. Our study enables to determine the optimal parameter values to operate the multi-Stokes laser in the low noise regime.

“…Conversely the EDFA response to amplitude fluctuations must be carefully taken into account due to coherent population oscillations (CPO) effect [30]. Indeed, under saturation, the optical gain varies with the input optical power at low frequency.…”

We propose a theoretical description and experimental validation of a frequency self-stabilized photonic oscillator. This photonic oscillator which relies on a solid-state laser and a nonreciprocal Brillouin fiber resonator (BFR) arranged in an optical phase-locked loop (OPLL) was recently shown to provide very narrow linewidth in the Hz range. Special attention is given to end up with analytical expressions relying on coupledmode formalism, of the BFR dynamics in which the non-resonant configuration for the pump has to be addressed. Furthermore, the transfer function of the full system is derived from the response of each component within the OPLL leading to two interleaved loops, relative to the phase and to the amplitude fluctuations of the optical field. An experimental setup including a solid-state Er:Yb laser is detailed and used to test the model predictions, both for phase noise level and response time. This model opens the way to the optimization of this new type of photonic oscillator which can be adapted to any kind of pump laser.

“…Unfortunately, for general rare earth ion-doped fiber amplifiers, their working frequency is limited to below several hundreds of Hz owing to the long lifetime of the stimulated ions [18]. In this way, the SOA has attracted more intense research in realizing laser noise suppression, thanks to its nanosecondlevel of carrier lifetime, which leads to a reduction bandwidth of up to GHz [19][20][21].…”

Significant suppression of the intensity noise of single-frequency fiber laser is demonstrated with a cascading semiconductor optical amplifier (SOA). Based on the nonlinear amplification dynamics of the SOA, intensity noise reduction would take place in every transmission of the laser signal. By cascading two SOAs, a maximum noise suppression of 30 dB at around the resonant relaxation oscillation (RRO) frequency as well as a suppression bandwidth of up to 50 MHz is realized. Moreover, the RRO peak is restricted to a significant narrow frequency band, outside of which the laser noise approaches the noise floor of the measurement. The remarkable amplified spontaneous emission (ASE) introduced by the SOA is entirely filtered out with a fiber Bragg grating (FBG). Furthermore, no noticeable degradation of laser frequency noise has been observed.
