Abstract

It has been shown that inhomogeneously broadened amplifiers strongly suppress the interchannel crosstalk that occurs when signals are added or rerouted in wavelength-multiplexed multiaccess networks. In a small system with only six gain stages, such crosstalk was suppressed by 11 dB. The magnitude of both the crosstalk in homogeneous systems and its suppression in inhomogeneous systems is expected to scale with the size of the network.<>
