40-GHz pulse train generation using soliton compression of a Mach-Zehnder modulator output

We demonstrate 40-GHz soliton pulse train generation using nonlinear compression of the output of a Mach-Zehnder modulator. This source generates transform-limited pulses at twice the RF drive frequency, requires less than V/sub /spl pi// drive level, is tunable in wavelength (over the entire EDFA bandwidth), and is tunable in repetition rate.<<ETX>>
