Effect the Radius of Air Holes in Photonic Crystal Fiber on Soliton Propagation with Different Orders

Mohammed Salim Jasim

Photonic Crystal Fibers (PCFs) with periodic structure are a never-ending and constantly evolving. In this study was designed fiber photonic crystal is proposed and proven through the Matlab program, which employs the SplitStep Fourier Method (SSFM). Among the consequences demonstrated and studied are the solitons in different order, The impact of changing the radius of air holes on the geography of solitone propagation during fiber has studied, and get supercontinuum generation by increasing the value of radius affecting the third-order soliton. This spectral expansion has important in many modern applications, including medical, industrial and military, as well as have an important role in communication systems.
