Abstract
This study is to obtain a better understanding of how to shape the pulse laser
spectrum by varying the material properties of the photonic crystal fiber (PCF). This
includes the ability to obtain spectral power in particular wavelength regions, and
obtaining a broad bandwidth.. Numerical modeling of the split step Adaptive Fourier
method has been used to solving a form of nonlinear Schrödinger equation, which
describes the propagation of pulses in PCF. It was investigated how the spectrum can
be controlled through dispersion property. The electromagnetic wave that send from
IR laser diode source through the PCF to the observer. the optical properties of this
electromagnetic wave, normalized power, intensity, dispersion, and group delay
dispersion will be studied for the input, output and observer laser pulse. The
compared of the different two materials of PCF (fused silica and Barium-fluoride
BaF2) that be used and studies.
