Low-Crosstalk 103 Channel$,times,$10 Gb/s (1.03 Tb/s) Wavelength Conversion With a Quasi-Phase-Matched LiNbO₃Waveguide

We propose a low-crosstalk multichannel wavelength conversion scheme based on a parametric process. Simultaneous wavelength conversion of 25 GHz spaced 103 channeltimes10 Gb/s (1.03 Tb/s) wavelength-division multiplexing signals with an 8- and 4-nm guard band is successfully demonstrated by using a quasi-phase-matched lithium niobate waveguide. The method is evaluated both theoretically and experimentally
