Bandwidth optical parametric amplifier by using photonic crystal fiber with pump depletion

摘要

Bandwidth gain characteristics of two-pump fiber optical parametric amplifier (FOPA) with photonic crystal fiber (PCF) are discussed. The pump depletion is considered in. Broader 62dB gain can be obtained in the range from 1370nm to 1790nm.The effects of dispersion characteristics of the PCF on the gain bandwidth are analyzed. And the influences of signal and pump powers are also taken into account. From the analysis that by properly selecting the PCF and setting the pump and signal powers, wider gain bandwidth can be achieved, which is useful for the dense wavelength diversion multiplexing (DWDM)system.
