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

A periodically poled LiNbO[SUB3] (PPLN) waveguide that simultaneously) converts the wavelengths of 25 GHz-spaced, 1.03 Tbit/s (103 × 10 Gbit/s) DWDM signals, from C-band to L-band, with the small guard band of 8 nm (4 nm × 2) is shown. The converted signals have Q-factors of at least 15.6 dB. [ABSTRACT FROM AUTHOR]
