Wavelength conversion and regeneration: To invert or not to invert?

Research output: Contribution to journalArticlepeer-review

Abstract

We investigate the operation of an all-optical wavelength converter/regenerator device, constructed from a nonlinear module and an interferometer. Nonlinear devices based upon cross-gain and cross-phase modulation will invert an input signal, and the interferometer's operating point can be chosen to re-invert or not re-invert the signal exiting the nonlinear device. It is proven that superior performance is obtained when the interferometer does not re-invert the signal. This result concurs with experimental reports.
