Abstract :
We present a quantum-mechanical analysis of a nonlinear interferometer that achieves optical switching via cross-phase modulation (XPM) resulting from the Kerr effect. We show how it performs as a very precise optical regenerator, highly improving the transmitted bit-error rate (BER) in the presence of loss.
