Abstract

A type of high-polarization-isolation optical parametric amplifier (OPA) is reported based on the difference-frequency generation (DFG) process and the sum-frequency generation (SFG) process in a periodically polarized lithium niobate (PPLN) waveguide. Two OPA schemes using x-cut and z-cut PPLN waveguides are proposed and numerically demonstrated. The simulation results show that, the output polarization isolation up to 39.77 dB and 35.68 dB can be obtained with x-cut and z-cut PPLN waveguides, respectively.
