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.

Supercontinuum Generation Assisted by Wave Trapping in Dispersion-Managed Integrated Silicon Waveguides

“…In 220-nm-thick structures, the group-velocity dispersion (GVD) depends strongly on the waveguide width and a net anomalous dispersion can be reached in the wavelength range of 1500-2300 nm. This indicates the possibility of dispersion management by modifying the silicon-core geometry, similarly to fibers [57,58]. However, as shown in Fig.…”

Customizing supercontinuum generation via on-chip adaptive temporal pulse-splitting

“…state-of-the-art imaging and metrology applications requiring both spectral and temporal tunability (e.g. pump-probe measurement techniques, hyperspectral imaging, or various schemes for coherent control) 4 – 8 , 14 , 16 , 34 .…”

“…In contrast, using more than one pulse to seed SC generation not only allows the excitation of multiple independent (intra-pulse) dynamics, but also leads to a richer variety of effects arising from the interaction of different components, i.e. inter-pulse effects such as multi-pulse soliton ejections, dispersive wave radiations, spectral superposition, steering, and collisions 3 , 30 – 34 . Yet, initial efforts towards this direction 32 , 33 , 35 – 38 have only partially unleashed the potential of this concept.…”

Genetic algorithm driven spectral shaping of supercontinuum radiation in a photonic crystal fiber

“…Evolutionary algorithms were also implemented to gain control and optimize the output SC spectrum [16,17]. We also mention numerical works in which genetic algorithms (GAs) were applied to determine the carrier wavelength, power and duration of the pump pulse to control the frequency location of solitonic components of the SC spectrum [18,19]. Whereas previous successful experiments [14,15] focused on gaining control over limited SC spectral range, in this study we experimentally demonstrate enhancement and shaping of pre-chosen spectral features over the full SC spectrum (excluding the spectral range of the pump pulse).…”
