Abstract
Based on the symmetric-pump phase-sensitive parametric amplifier (SP-PSA) model in silicon waveguide, the gain and phase generation characteristics of SP-PSA in the presence of two-photon absorption (TPA) are investigated. Different parameters of pumps and medium have been considered to illustrate their effect on SP-PSA. The results show that the net gain and low noise can be only achieved with appropriate pump power and free carrier lifetime while dispersion is not very important. In addition, the phase regeneration performance can also be influenced by pump and medium parameters.
