    "abstract": "We numerically study supercontinuum (SC) generation in photonic crystal\nfibers pumped with low-power 30-ps pulses close to the zero dispersion\nwavelength 647nm. We show how the efficiency is significantly improved by\ndesigning the dispersion to allow widely separated spectral lines generated by\ndegenerate four-wave-mixing (FWM) directly from the pump to broaden and merge.\nBy proper modification of the dispersion profile the generation of additional\nFWM Stokes and anti-Stokes lines results in efficient generation of an 800nm\nwide SC. Simulations show that the predicted efficient SC generation is more\nrobust and can survive fiber imperfections modelled as random fluctuations of\nthe dispersion coefficients along the fiber length.",
