Abstract :
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 >30 dB to <1 dB
