“…Figure 3 is a sketch of the second experimental setup for mapping the SBS frequency shift. This distributed measurement is based on a recently-developed pump-probe technique called Brillouin optical time domain analysis (BOTDA) [10]. A CW DFB laser source at 1557 nm, similar to that of the previous setup, was split into pump and probe waves.…”

“…By simply varying the frequency of the continuous probe wave relatively to the pump frequency, the Brillouin gain spectrum could then be fully retrieved at any location along the fiber and the Brillouin shift (ν B ) be unambiguously determined as a function of distance. This method offers several advantages such as no laser frequency drift dependence and no need for a tunable laser source [10]. Since the spatial resolution is given by the pulse duration, we performed two experiments with pulse durations of 20ns and 100ns, respectively.…”

“…We found that the SBS threshold increases threefold compared with a uniform all-silica fiber and that this is in quite good agreement with the Brillouin linewidth broadening by 80 MHz. Then, we present position-resolved mapping of the Brillouin frequency shift using Brillouin optical domain time analysis (BOTDA) [10]. The results of our measurements show a broad asymmetric SBS gain spectrum distributed all along the fiber and indicate that the structural variations of the PCF have actually little impact on the Brillouin frequency shift.…”

Abstract:We provide a complete experimental characterization of stimulated Brillouin scattering in a 160 m long solid-core photonic crystal fiber, including threshold and spectrum measurements as well as positionresolved mapping of the Brillouin frequency shift. In particular, a three-fold increase of the Brillouin threshold power is observed, in excellent agreement with the spectrally-broadened Brillouin gain spectrum. Distributed measurements additionally reveal that the rise of the Brillouin threshold results from the broadband nature of the gain spectrum all along the fiber and is strongly influenced by strain. Our experiments confirm that these unique fibers can be exploited for the passive control or the suppression of Brillouin scattering. Brillouin shift along single-mode optical fibres," Opt.

“…In these simulations we used the experimental power spectrum of the laser with a random spectral phase on each longitudinal mode [10,27]. There are three key reasons to use this "phenomenological" model: first, high-power fiber lasers exhibit fast intensity instabilities on the time scale of the coherence of the source, as shown by autocorrelation measurements in reference [10].…”

“…We believe that this difference is due to longitudinal fluctuations of the dispersion. Some measurements in standard telecommunication fibers [27] have shown that these variations of dispersion can be extremely important, specially if we consider that the fiber is relatively old and unconventional. To confirm it, we measured the dispersion in two pieces of 100 m at each end of the 6 km fiber with a pulsed laser at 1550 nm by looking at the location of MI side lobes.…”

Spectrally-bounded continuous-wave supercontinuum generation in a fiber with two zero-dispersion wavelengths

et al. 2008

A common issue in fiber-based supercontinuum (SC) generation under\ud continuous-wave pumping is that the spectral width of the resulting source is related\ud to the input power of the pump laser used. An increase of the input pump power\ud leads to an increase of the spectral width obtained at the fiber output, and therefore,\ud the average power spectral density (APSD) over the SC spectrum does not grow\ud according to the input power. For some applications it would be desired to have a\ud fixed spectral width in the SC and to increase the average PSD proportionally to the\ud input pump power. In this paper we demonstrate experimentally that SC generation\ud under continuous-wave (CW) pumping can be spectrally bounded by using a fiber\ud with two zero-dispersion wavelengths (ZDWs). Beyond a certain pump power, the\ud spectral width of the SC source remains fixed, and the APSD of the SC grows with\ud the pump power. In our experiment we generate a reasonably flat, spectrally-bounded\ud SC spanning from 1550 nm to 1700 nm. The spectral width of the source is shown to\ud be constant between 3 and 6 W of pump power. Over this range, the increase in input\ud power is directly translated in an increase in the output APSD. The experimental\ud results are confirmed by numerical simulations, which also highlight the sensitivity\ud of this configuration to variations in the fiber dispersion curve. We believe that these\ud results open the way for tailoring the spectral width of high-APSD CW SC by\ud adjusting the fiber dispersion.Ministerio de Educación y CienciaComunidad de MadridConsejo Superior de Investigaciones CientíficasConseil Régional du Nord Pas de Calai
