Abstract

All-optical wavelength conversion is considered to be a key technology in future high-speed large-capcity dense wavelength-division-multiplexed (DWDM) optical networks. Transparent wavelength conversion is highly desired especially for various advanced modulation formats. We report a novel 40 Gbit/s all-optical transparent frequency-shift keying (FSK) wavelength conversion and logic NOT gate by exploiting cascaded second-harmonic generation and difference-frequency generation (cSHG/DFG) in a periodically poled lithium niobate (PPLN) waveguide. In addition, transparent wavelength conversions for optical duobinary (ODB) and alternate-mark inversion (AMI) modulation formats are demonstrated in the experiment.
