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 Gbit / s is successfully updated, with an optical signal-to-noise ratio (OSNR) penalty of 2 dB for return-to-zero and 4 dB for non-return-to-zero at a bit-error rate (BER) of 2 × 10 3 . Simultaneous processing of four wavelength-multiplexed 16-QAM signals with an average OSNR penalty of 4.5 dB at a BER of 2 × 10 3 is also demonstrated.
