Data-Polarization-Insensitive Wavelength Conversion in a PPLN Waveguide by Cross-Polarization-Modulation of the Pump using an SOA

摘要

We demonstrate a novel method of wavelength-conversion in a PPLN-waveguide using polarization-modulation of its pump. Polarization-insensitive, all-optical, intensity-to-polarization conversion in an SOA is used to reduce the PPLN waveguide's polarization-sensitivity from >30dB to<1dB.
