Gigabit all-optical shift register and it´s perspective application for photonic past packet switches

The demonstration of an all-optical shift register is introduced by using a master-slave integrated configuration of self electro-optic effect devices. The system structure, system performance and some possible improvements are presented. The dependence of the switching performance is discussed by analyzing the device´s transmission coefficients and absorption coefficients. Based on these performance analyses, an improved scheme is discussed, which can provide a 2 Gbps throughput. Considering its advantage of application in optical storing, optical computing, optical wavelength converting and optical modulating, we presented the application of this all-optical shift register in optical fast packet switches
