All-Normal-Dispersion Photonic Crystal Fibers Under Prism of Supercontinuum Generation and Pulse Compression

We discuss properties of all-normal-dispersion photonic crystal fibers in context of supercontinuum generation and compression of ultrashort pulses. The application of pump pulses typical for the state of the art Ti:Sapphire lasers allows obtaining quite flat and broad spectra extending more than one octave in this fiber. The influence of initial pump pulse parameters such as pulse energy, duration, and pump wavelength on the SC generation was investigated. It was shown that compression of pulses with such SC spectra allows obtaining a few cycle pulses up to 8.1 fs, if a simple quadratic compressor is used and single cycle pulses up to 2.5 fs, if full phase compensation is provided.

Formation of Femtosecond Parabolic Pulses in Normal-Dispersion Optical Fibers

We have shown through extensive numerical simulations that application of passive nonlinear reshaping in normal-dispersion optical fibers could produce femtosecond parabolic pulses (a few hundreds fs) modern femtosecond lasers and commercially available fibers.
