...This means that the output extinction ratio can be evaluated from the static transmission function . It should be noted that the large-signal theory can easily be extended to arbitrary bit rates since (5) and (6) are the same in a retarded time frame [ 23 ]....

...The large gain of long amplifiers reduces the stimulated carrier lifetimes to values of the order of tens of picoseconds and propagation effects also increase the amplifier bandwidth [9], [10]....

...Well-established methods for all-optical wavelength conversion based on the use of semiconductor optical amplifier (SOA) as an active nonlinear medium are cross-gain modulation [1], [2] cross-phase modulation [2], and four-wave...

...Although error-free wavelength conversion at a bit rate close to the small-signal bandwidth can be performed [2], if several wavelength conversion stages are required, or if the requirements on the pulse rise and fall times of the converted signal are stringent, the maximum allowable bit rate may only be typically a tenth of the small-signal bandwidth....
