Soliton self-compression in a photonic crystal fiber with dispersion optimized for pumping near 1300 nm

In this paper, we have designed a high nonlinear photonic crystal fiber (HN-PCF) based on square-lattice geometry with the zero dispersion wavelength (ZDW) around 1300 nm. We came up to realize pulse compression of 28.4 fs around 1300 nm by the generation of solitons of different orders to obtain ultrashort pulses. First, we obtain 4 fs pulses in a PCF length of 66cm, then, we improved the pulse compression until 1.2 fs in a PCF length of 26 cm.This new design of the PCF could be applied for supercontinuum generation witch would be used in Optical Coherence Tomography for high resolution biomedical imaging.
