D. Norte et Ae. Willner, EXPERIMENTAL DEMONSTRATION OF A MULTIPLE-LAMBDA WAVELENGTH SHIFTER FOR DYNAMICALLY RECONFIGURABLE WDM NETWORKS, IEEE photonics technology letters, 9(7), 1997, pp. 922-924
We demonstrate a multiple-lambda wavelength shifter that is based on t
emporal interleaving and semiconductor optical amplifier cross-gain co
mpression. Our multiple-lambda wavelength shifter is transparent to bo
th the nonreturn-to-zero (NRZ) and return to-zero (RZ) input data-form
ats. We simultaneously wavelength shift two independent NRZ 1-Gb/s WDM
channels from 1548 and 1552 nm to 1540 and 1569 nm, respectively, wit
h low-power penalties.
