Abstract

We have designed and developed a nonlinear-optic wavelength converter with periodically poled LiNbO₃ (PPLN) waveguides for optical fiber communication systems. The wavelength conversion module comprises two parallel PPLN ridge waveguide devices for a polarization-independent operation. We demonstrate highly efficient wavelength conversions and amplifications based on a cascaded second harmonic generation (SHG) and difference frequency generation (DFG), and optical parametric amplifier (OPA). The wavelength conversion efficiencies and the signal gains more than 20 dB are achieved for both orthogonal transverse magnetic (TM) polarization and transverse electric (TE) polarization in the module.
