Simultaneous 25 GHz-spaced DWDM wavelength conversion of 1.03 Tbit/s (103/spl times/10 Gbit/s) signals in PPLN waveguide

A periodically poled LiNbO/sub 3/ (PPLN) waveguide that simultaneously converts the wavelengths of 25 GHz-spaced, 1.03 Tbit/s (103 /spl times/10 Gbit/s) DWDM signals, from C-band to L-band, with the small guard band of 8 nm (4 nm/spl times/2) is shown. The converted signals have Q-factors of at least 15.6 dB.
