Gm. Dariano et P. Kumar, A QUANTUM-MECHANICAL STUDY OF OPTICAL REGENERATORS BASED ON NONLINEAR-LOOP MIRRORS, IEEE photonics technology letters, 10(5), 1998, pp. 699-701
We present a quantum-mechanical analysis of a nonlinear interferometer
that achieves optical switching via cross-phase modulation (XPM) resu
lting 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.
