Abstract :
Summary form only given.All optical temporal-spatial conversion techniques using a four-wave-mixing (FWM) process have been developed in the 1990s. The performance of these techniques is determined by the FWM mechanism. The authors demonstrated the serial-to-parallel conversion with large efficiency and fast response time using the excitonic /spl chi//sup (3)/ nonlinearity in ZnSe film. However, the performance was achieved only in low temperature (10 K), because the excitonic nonlinearity of the ZnSe film smears out in room temperature Here we report on serial-to-parallel conversion using a material that has large third order nonlinearity and fast response time in room temperature. The material is a self-organized quantum-well system consisting of inorganic well layers and organic barrier layers. We demonstrate serial-to-parallel conversion of Tbits/s signals with conversion rate of 100 GHz.
