The nonlinear propagation of femtosecond pulses in photonic-crystal fibers is investigated theoretically without the use slowly varying envelope approximation. Low-intensity supercontinuum generation caused by fission higher-order solitons into red-shifted fundamental and blue-shifted nonsolitonic radiation studied a large range fiber pulse parameters. It shown that phase matching degenerate four-wave mixing can be achieved an extremely broad frequency from IR to UV. Spontaneous new components parametric amplification as well its possible overlap with soliton are detail.
