All-optical sub-Tbits/s serial-to-parallel conversion using excitonic giant nonlinearity

An all-optical serial-to-parallel conversion technique, which is the inverse process of the real-time pulse shaping, is reported. A conversion of 0.14-Tbits/s signals using excitonic-giant nonlinearity of ZnSe film is reported. The response of this conversion system is faster than 13 ps with a conversion efficiency of 0.1%.
