Abstract

The data packet buffering can be implemented in dual loop optical buffer DLOB through crossphase modulation XPM between the control signal and the data packets However the output equality of dual wavelength signals will degrade due to the unbalanced gain and phase shift This problem can be resolved by power equalization using the saturation characteristics of SOA The data packets with 25 Gb/s can be buffered in DLOB for 16 cycles corresponding to 165 μsThe extinction ratio of the output packet is 8 dB while the S/N is 81 dB
