206-channel chirped-pulse wavelength-division multiplexed transmitter

The authors demonstrate a record 206-channel wavelength-division multiplexed transmitter, using a single femtosecond laser at 1.55 /spl mu/m and a single time-division multiplexed electroabsorption modulator. The channel spacing is /spl sim/37 GHz (0.3 nm), and the bit rate in each channel is 36.7 Mbit/s.
