“…Then, under a cut-off frequency f 1 given by the upper level lifetime, the intensity variations of the incoming beam will be almost annihilated. Conversely, above a second cut-off frequency f 2 given by the upper level lifetime and the gain compression coefficient, the intensity variations are amplified [31]. The EDFA will then act as a high pass filter.…”

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.

“…Furthermore, the insertion of the optical filter leads to a significant enhancement of noise (Shumakher et al, 2009b). Besides, four-wave mixing in SOA have been enhanced by modulating the current of the SOA (Capmany et al, 2002), but the resulting phase shift has never been studied before the recent theoretical study by Anton et al (2009), which points out the enhancement of phase shift by forced CPO. The first experimental observation and a simple physical interpretation of forced CPO is presented in (Berger, Bourderionnet, de Valicourt, Brenot, Dolfi, Bretenaker & Alouini, 2010).…”

“…4. The microwave gain |S 21 | present a high pass filter behavior, usually observed in SOAs (Boula-Picard et al, 2005), and is associated to an interesting phase shift, which presents a linear variation at low frequency, with a slope tunable through the injected current or the optical input power: a key characteristic to set up a tunable delay line (see Fig. 2).…”
