Abstract
A semiconductor optical amplifier (SOA) that has an inverse-shaped transfer
function to that of an electroabsorption modulator (EAM) is used to reduce
the nonlinearity of the EAM. An SOA operates in the gain saturation region
, and the increased gain of the SOA is preferred for an improved dynamic ra
nge. A 9 dB enhancement of the SFDR is theoretically obtained. (C) 2000 Joh
