Cross phase modulation in a five--level atomic medium: Semiclassical theory
Carlo Ottaviani, Stojan Rebic, David Vitali +1
The interaction of a five-level atomic system involving electromagnetically induced transparency with four light fields is investigated. Two different light-atom configurations are…

Polarization phase gate with a tripod atomic system
S. Rebic, D. Vitali, C. Ottaviani +4
We analyze the nonlinear optical response of a four-level atomic system driven into a tripod configuration. The large cross-Kerr nonlinearities that occurr in such a system are sho…
