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.

All-Normal Dispersion Photonic-Crystal Fiber for Pulse-Preserving Supercontinuum Generation near 800 nm

All-normal dispersion photonic-crystal fiber is designed for pulse-preserving supercontinuum generation near 800 nm. Supercontinuum generation is analyzed numerically addressing the role of pump pulse energy and offset of the pump wavelength from the zero point of 3d-order dispersion.
