Abstract

A wide band, high saturation power InAs/InP 1550 nm quantum dash optical amplifier is reported. The dependence of crosstalk in multiwavelength amplification on bit rate, power and channel detuning is studied. Amplification of an eight channel WDM signal covering a 100 nm bandwidth with no crosstalk is demonstrated.
