Abstract
The artificial resonance of optical ring resonators can be used to enhance the nonlinear phase shift resulting from a third-order material response. This enhancement results form the interaction of two effects: the internal intensity build up within the resonator which introduces a single pass nonlinear phase shift, and the resulting detuning of the resonance which causes a change in phase at the outputs. Devices consisting of multiple resonators in series can provide additional improvements in terms of allowing a large phase shift of the output. As compared to same material in bulk, devices consisting of single and multiple ring resonators constructed from an absorbing material can provide a much greater nonlinear phase shift, in some case by many orders of magnitude. In addition, these phase shifts exceed the maximum value allowed by absorption in bulk materials.
