Query: Distributed Kerr Nonlinearity in a Coherent All-Optical Fiber-Ring
  Reservoir Computer   We investigate, both numerically and experimentally, the usefulness of a
distributed nonlinearity in a passive coherent photonic reservoir computer.
This computing system is based on a passive coherent optical fiber-ring cavity
in which part of the nonlinearities are realized by the Kerr nonlinearity.
Linear coherent reservoirs can solve difficult tasks but are aided by nonlinear
components in their input or output layer. Here, we compare the impact of
nonlinear transformations of information in the reservoir input layer, its bulk
- the fiber-ring cavity - and its readout layer. For the injection of data into
the reservoir, we compare a linear input mapping to the nonlinear transfer
function of a Mach Zehnder modulator. For the reservoir bulk, we quantify the
impact of the optical Kerr effect. For the readout layer we compare a linear
output to a quadratic output implemented by a photodiode. We find that optical
nonlinearities in the reservoir itself, such as the optical Kerr nonlinearity
studied in the present work, enhance the task solving capability of the
reservoir. This suggests that such nonlinearities will play a key role in
future coherent all-optical reservoir computers.
