Technology Opportunities

Coherent optical transceivers are widely deployed in metropolitan, long-haul and ultra long-haul fiber optic networks. Their performance in terms of sensitivity and data-rate is unparalleled, but their cost is high, in large part because they rely on an expensive optical front end in the ...

ObjectivesThe theoretical research has led to the understanding that the effects of the nonlinear interference (NLIN) between the various channels in wavelength division multiplexed (WDM) environment can be described as time-varying inter-symbol interference (ISI) between the samples of the ...

Nonlinear interference noise (NLIN) is arguably the most important factor limiting the capacity of fiber-optic communication systems. It is customary to classify nonlinear phenomena as either intra-channel, or inter-channel. Intra-channel effects relate to the nonlinear distortions undergone by ...
