Bending What is Optical Fiber Dispersion?
... Since each mode ray travels a different distance as it propagates, the ray arrive at different times at the fiber output. So the light pulse spreads out in time which can cause signal overlapping so seriously that you cannot distinguish them any more.. ...

Creation of entangled states in coupled quantum dots via adiabatic... C. Creatore, R. T. Brierley, R. T. Phillips,
... We now show how this adiabatic protocol can be generalized to create entanglement in ensembles of coupled quantum dots, in which there are significant fluctuations in the dot energy. In this case, the entanglement pulse can be spectrally tuned to address a specific pair of dots; several entangled pa ...
