Abstract
A new 2 X 2 ATM photonic wavelength switching block has been presented. It is composed of wavelength beacon, wavelength filter and splitter, 2 X 2 LiNbO2 waveguide switches and optical buffer. Different input-line cells will be converted into the cells with the different wavelengths according to their destination address by the wavelength beacon. With the wavelength routing tag, the cell could be self-routed to the destination output-line. The routing path is both low loss and los noise. ATM cell contention is settled by an optical buffer in which the fiber delay-line, LiNbO3 waveguide switches and nonlinear semiconductor optical amplifiers are employed. Composed by various delay fibers and waveguide switches, the buffer can store 7 cells or more. This block can be easily reconfiguration and extended to the 4 X 4, 8 X 8 ATM photonic switching system. It can be used as ATM switching unit and optical cross connection component in the all optical networks. The ATM input line bit rate of our photonic switching block is 2 X 622 Mbit/s.
