Limits of coherent supercontinuum generation in normal dispersion fibers
We study the largely unexplored transition between coherent and noise-seeded incoherent continuum generation in all-normal dispersion (ANDi) fibers and show that highly coherent supercontinua with spectral bandwidths of one octave can be generated with long pump pulses of up to 1.5 ps duration, corresponding to soliton orders of up to N 600. In terms of N , this corresponds to an approximately ...
متن کاملCoherent supercontinuum generation in photonic crystal fiber with all-normal group velocity dispersion
We demonstrate supercontinuum generation in a photonic crystal fiber with all-normal group velocity dispersion. Pumping a short section of this fiber with compressed pulses from a compact amplified fiber laser generates a 200 nm bandwidth continuum with typical self-phasemodulation characteristics. We demonstrate that the supercontinuum is compressible to a duration of 26 fs. It therefore has a...

متن کاملModelling of high-power supercontinuum generation in highly nonlinear, dispersion shifted fibers at CW pump.
For the first time a remarkably exact match was achieved of the results from modelling of CW-pumped SC in a highly non-linear fibre with experiment (A.K. Abeeluck et al. Opt. Lett. 29, 2163-2165 (2004)) where a wide-band SC in the 1200-1780-nm range was reported. Our simulation results show that decay of CW pump radiation into a train of sub-picosecond pulses induced by the modulation instabili...
متن کاملDynamics of Raman soliton during supercontinuum generation near the zero-dispersion wavelength of optical fibers.
We observe unique dynamics of Raman soliton during supercontinuum process when an input pulse experiences initially normal group-velocity dispersion with a negative dispersion slope. In this situation, the blue components of the spectrum form a Raman soliton that moves faster than the input pulse and eventually decelerates because of Raman-induced frequency downshifting. In the time domain, the...
