| Abstract | Subchannel data updating of high-order modulation format signals using cascaded sum- and difference-frequency generation in a single periodically poled lithium niobate waveguide is demonstrated. One quadrature phase-shift-keying subchannel of a 16-quadrature amplitude modulation (QAM) signal at 40&\#x2009;&\#x2009;Gbit/s is successfully updated, with an optical signal-to-noise ratio (OSNR) penalty of &\#x223C;2&\#x2009;&\#x2009;dB for return-to-zero and &\#x223C;4&\#x2009;&\#x2009;dB for non-return-to-zero at a bit-error rate (BER) of 2&\#xD7;10&\#x2212;3. Simultaneous processing of four wavelength-multiplexed 16-QAM signals with an average OSNR penalty of 4.5&\#xA0;dB at a BER of 2&\#xD7;10&\#x2212;3 is also demonstrated. |
