We investigate dual pump Fiber Optical Parametric amplifier (FOPA) for wide gain bandwidth. With careful optimization of parameters of fiber used for amplification, dual pump FOPAs can effectively serve as high gain saturated, broadband amplifiers. Type of fiber and its characteristics strongly affect the peak gain and bandwidth of the dual pump FOPA. We attempt to optimize the fiber parameters for maximized gain in dual pump FOPAs. Simulation results are based on analytical modeling of dual pump FOPA. Based on these investigation results we demonstrate a flat gain amplifier with peak gain of 38 dB over wide bandwidth of 228 nm using short length Photonic crystal Fibers (PCFs) with high non-linearity (γ>50). We also demonstrate improved gain saturation in dual pump over single pump FOPA.

Abstract


We investigate dual pump Fiber Optical Parametric amplifier (FOPA) for wide gain bandwidth. With careful optimization of parameters of fiber used for amplification, dual pump FOPAs can effectively serve as high gain saturated, broadband amplifiers. Type of fiber and its characteristics strongly affect the peak gain and bandwidth of the dual pump FOPA. We attempt to optimize the fiber parameters for maximized gain in dual pump FOPAs. Simulation results are based on analytical modeling of dual pump FOPA. Based on these investigation results we demonstrate a flat gain amplifier with peak gain of 38 dB over wide bandwidth of 228 nm using short length Photonic crystal Fibers (PCFs) with high non-linearity (γ>50). We also demonstrate improved gain saturation in dual pump over single pump FOPA.
