Abstract :
The authors show experimentally and theoretically that the bandwidth for wavelength conversion through cross-gain modulation varies approximately linearly with the length of the amplifier. By cascading two similar semiconductor optical amplifiers, the small-signal wavelength conversion bandwidth is doubled
