✦ Synopsis

terned data, the 80-GHz loop mirrors are placed after the compressed pulse trains. The 80-GHz loop mirror works as a precise multiplexer where the pulses are 25-ps delayed and multiplexed inside the loop mirror [9,10]. Thus, the 10-GHz pulses from the gain-switched laser are combined into 80-Gb/s 01100000 patterned data with the wavelength of 1550 nm ( 2 ), while the mode-locked 20-GHz pulses are interleaved into the patterned data of 11001100 with the 1555-nm ( 1 ) wavelength. Since the AND operation results are only carried by a 1550-nm data stream, a 1-nm bandpass filter (BPF) centered at 1550 nm is inserted before the results are observed using a 50-GHz sampling oscilloscope. In this experiment, the 11001100 patterned data are coupled into port 1 of the MZI and the 1550-nm 80-Gb/s patterned data are launched into port 2 and is selected by the BPF after cross-phase modulation in the SOA-MZI. A beam of CW light with wavelength of 1545 nm ( 3 ) is sent into port 3. During the operation, the average launched power of both patterned data are 10 dBm, and the average power of CW light is set at 0.75 dBm before it's sent into port 4. Figure 5 illustrates oscilloscope traces of the input data pattern of 11001100 and 01100000, and the logic AND output as well, that is, only if both input are 1, the corresponding output is 1, which matches the simulation results in Figure 2.
