.Investigation on noise characteristics of dual-pumped fiber optical parametric amplifiers based on photonic crystal fibers[J].Optoelectronics Letters,2010,6(3):168-171 Investigation on noise characteristics of dual-pumped fiber optical parametric amplifiers based on photonic crystal fibers 凌婧 Laboratory;Information;Photonics;Optical;Communications;Beijing;University;Posts;Telecommunications; Abstract:       The noise characteristics of dual-pumped fiber optical parametric amplifiers(FOPAs) induced by gain and loss in photonic crystal fibers(PCFs) are analyzed.A special photonic crystal fiber is designed.Its noise figure(NF) changes with structure parameters,and it decreases as the hole diameter decreases.Three factors including input-signal power,signal wavelength and pump separation which impact on the final noise figure are discussed with the designed PCF.
