“…First, we have observed and explained for the first time (to the best of our knowledge) a process in which a RR radiated from a soliton emits a new cascaded RR when crossing the evolving ZDW of the fiber. Second, we have provided first experimental results showing the emission of multiple RRs from a unique soliton in a dispersion-varying optical fiber, following the numerical work in [20]. Third, we have experimentally observed for the first time the generation of a polychromatic RR, as was previously numerically investigated in [19], leading to a RR continuum spanning over 500 nm.…”

“…Recently, it has been shown with numerical simulations that a single Raman shifting soliton can generate a polychromatic RR in a suitably engineered tapered fiber such that the ZDW remains close enough to the soliton spectrum throughout propagation [19]. Following the same idea, it has been shown numerically that multiple RRs can be generated from a single fundamental soliton in an axially segmented fiber by sequentially hitting the ZDW, which progressively shifts toward long wavelengths in order to follow the SSFS [20].…”

Temporal solitons propagating in the vicinity of a zero-dispersion wavelength in an optical fiber emit phasematched resonant radiations (RRs) as a result of perturbations due to higher-order dispersion effects. These RRs propagate linearly and they usually rapidly spread out in time, thus having a very low peak power. Here, we show that the use of an engineered dispersion-varying optical fiber allows us to induce a completely new dynamics, in which a new physical mechanism-cascade of RRs-is discovered. It is explained by the fact that the RR is temporally recompressed thanks to the change of dispersion sign induced by the varying geometry along the fiber. In addition, we report the experimental evidence of physical processes that had remained unobserved experimentally so far, such as the emission of multiple RRs from a single soliton and the generation of a 500 nm continuum exclusively composed of polychromatic RRs.

“…DW is an important physical mechanism for supercontinuum (SC) generation, and its frequency is determined by the nonlinear phase-matching (PM) condition with the soliton [6][7][8]. Since the initial discovery by Beaud et al [5], many researches on DW have been conducted involving various optical fibers, such as photonic crystal fibers (PCFs) and chalcogenide microstructured optical fibers (MOFs) [9][10][11][12][13].…”

We experimentally demonstrate multiple dispersive waves (DWs) emitted by multiple mid-infrared solitons in a birefringence tellurite microstuctured optical fiber (BTMOF). To the best of our knowledge, this is the first demonstration of multiple DWs in the non-silica fibers. By using a pulse of ~80 MHz and ~200 fs emitted from an optical parametric oscillator (OPO) as the pump source, DWs and solitons are investigated on the fast and slow axes of the BTMOF at the pump wavelength of ~1800 nm. With the average pump power increasing from ~200 to 450 mW, the center wavelength of the 1st DW decreases from ~956 to 890 nm, the 2nd DW from ~1039 to 997 nm, the 3rd DW from ~1101 to 1080 nm, and the 4th DW from ~1160 to 1150 nm. Meanwhile, obvious multiple soliton self-frequency shifts (SSFSs) are observed in the mid-infrared region. Furthermore, DWs and solitons at the pump wavelength of ~1400 and 2000 nm are investigated at the average pump power of ~350 mW.

“…[3,4] for a review on the topic). To mention only a few examples, light trapping [5], multi-peak soliton states [6][7][8], emission of Airy waves [9], intense dark-soliton SC [10] or broad and intense blue shifted polychromatic dispersive waves [11,12], would not be possible (or strong enough) without the SSFS. One of the most notorious feature of the Raman effect in SC generation with femtosecond pulses corresponds to the Raman soliton carrying the lowest frequency.…”

, FR.; Milián Enrique, C.; Torres-Gómez, I.; Torres-Cisneros, M.; Ferrando Cogollos, A. (2014). Supercontinuum optimization for dual-soliton based light sources using genetic algorithms in a grid platform. Optics Express. 22(19) Abstract: We present a numerical strategy to design fiber based dual pulse light sources exhibiting two predefined spectral peaks in the anomalous group velocity dispersion regime. The frequency conversion is based on the soliton fission and soliton self-frequency shift occurring during supercontinuum generation. The optimization process is carried out by a genetic algorithm that provides the optimum input pulse parameters: wavelength, temporal width and peak power. This algorithm is implemented in a Grid platform in order to take advantage of distributed computing. These results are useful for optical coherence tomography applications where bell-shaped pulses located in the second near-infrared window are needed.
