“…FWM can be performed in the semiconductor optical amplifier or fiber, generally, the wavelength conversion based on the FWM in fiber can operate at a higher speed, while in the SOA is limited by the carrier dynamics [8]. The relatively low non-linearity presented by the dispersion-shifted fiber (DSF) requires the use of long length [9]. As a consequence it is very difficult to control and stabilize the conversion device.…”

By use of the coupled equations of pump, signal and idler field, this paper have derived the gain expression of fiber optical parametric amplifier with high-order dispersion and high nonlinear optics. It is indicated that the optical parametric amplifier's gain is dependent of pump wavelength near zero dispersion wavelength. Gain and bandwidth are better when pump wavelength is close to zero dispersion wavelength. But when the difference of pump wavelength and zero dispersion wavelength exceeds some value, gain and bandwidth are smaller. If pump power is not exhausted, gain is linear with transmission distance.

“…However, efficiency of the underlying four-wave mixing (FWM) process depends critically on the relative polarizations of the pump and signal. Several schemes have been proposed to solve this problem but they require either a polarization-diversity scheme [2] or a Faraday rotator [3]. In a recent experiment, a polarization-maintaining fiber was used to separate temporally the two polarization components of the signal before launching it into a FOPA [4].…”

We propose a novel design for making the gain of single-pump, fiber-optic parametric amplifiers polarization independent. We show that under suitable conditions, signal gain varies by < 0.1 dB as its polarization varies.Single-pump fiber-optic parametric amplifiers (FOPAs) are attractive because they can be used for broadband amplification, wavelength conversion and other applications requiring ultrafast signal processing [1]. However, efficiency of the underlying four-wave mixing (FWM) process depends critically on the relative polarizations of the pump and signal. Several schemes have been proposed to solve this problem but they require either a polarization-diversity scheme [2] or a Faraday rotator [3]. In a recent experiment, a polarization-maintaining fiber was used to separate temporally the two polarization components of the signal before launching it into a FOPA [4].We propose a relatively simple, new scheme in which the pump and signal are launched into a birefringent fiber consisting of two sections such that the slow and fast axes are reversed in the second half of the fiber. The pump is launched at 45 • to these axes while the signal polarization can vary over the entire Poincaré sphere. We show theoretically that the FOPA gain varies by < 0.1 dB under such conditions.The total optical field is composed of the pump, signal and idler at frequencies ω p , ω s and ω i such that ω i = 2ω p − ω s . Its two polarization components satisfy the following two coupled nonlinear Schrödinger equations [5]:
