Df. Geraghty et al., WAVELENGTH CONVERSION FOR WDM COMMUNICATION-SYSTEMS USING 4-WAVE-MIXING IN SEMICONDUCTOR OPTICAL AMPLIFIERS, IEEE journal of selected topics in quantum electronics, 3(5), 1997, pp. 1146-1155
Four-wave mixing (FWM) in semiconductor optical amplifiers is an attra
ctive mechanism for wavelength conversion in wavelength-division multi
plexed (WDM) systems since it provides modulation format and bit rate
transparency over wide tuning ranges. A series of systems experiments
evaluating several aspects of the performance of these devices at bit
rates of 2.5 and 10 Gb/s are presented, Included are single-channel co
nversion over 18 nm of shift at 10 Gb/s, multichannel conversion, and
cascaded conversions, In addition time resolved spectral analysis of w
avelength conversion is presented.
