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 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 device transmission coefficients and absorption coefficients. Based on these performance analyses, an improved scheme is discussed, which can provide 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 alloptical shift register in optical fast packet switches.
