Noise Figure Evaluation of Polarization-insensitive Single-pump Fiber Optical Parametric Amplifiers

Several polarization-insensitive configurations for single-pump phase-insensitive fiber optical parametric amplifier are experimentally evaluated using 35GBaud PDM-QPSK signals. An equivalent noise figure of 9.1±1dB is experimentally derived by comparison with a variable noise figure EDFA. © 2020 The Authors.
