EXTREMELY HIGH DEGREE OF N-SOLITON PULSE-COMPRESSION IN AN OPTICAL FIBER

The process of pulse self-compression in an optical fiber is theoretically investigated on the basis of exact N-soliton solutions of the NLS. It is shown that the degree of compression can be approximately N times higher than in the previously considered case of N/coshtype initial conditions. The evolution of the spectra of N-soliton pulse is also considered.
