It has been shown that the generated supercontinuum light source fluctuates up to 50% of its output temporal intensity profile due to noises of different sources. The simulation method devised has been applied to the propagation of finite energy Airy pulse in a photonic crystal fiber and to study the generated noise.</p> <p style="margin: 0px;"></p> <p style="margin: 0px; text-align: justify;"></p> Airy pulse, Light propagation, Noises, Supercontinuum generation. 127 134 http://ijop.ir/browse.php?a_code=A-10-612-1&slc_lang=en&sid=1 Abolfazl Safaei abolfazl_safaei@live.com 10031947532846002678 10031947532846002678 No Department of Photonics, Graduate University of Advanced Technology Mohammad Agha Bolorizadeh mabolori@uk.ac.ir 10031947532846002679 10031947532846002679 Yes Department of Physics, Yazd University
