Flat and ultra-broadband two-pump fiber optical parametric amplifiers based on photonic crystal fibers

摘要: A two-pump fiber optical parametric amplifier (FOPA) based on the photonic crystal (PCF) in telecommunication region is investigated numerically. The loss and pump depletion are considered. influences of length, input signal power, center wavelength gain bandwidth, flatness, peak discussed. 6-wave model-based analysis FOPA also achieved compared with that 4-wave model; furthermore, properties model optimized investigated. comparison results show PCF-based achieves flatter wider spectra less length power to normal highly nonlinear fiber, where obtained great potential for communication system.
