【 摘 要 】

All-optical AND/XOR gates are proposed for non-return-to-zero (NRZ) data using semiconductor optical amplifier-based Mach-Zehnder interferometers (SOA-MZIs). For AND/XOR gates, the complementary data is applied as input to SOA-MZIs to enhance the operation data rate for NRZ signal up to 40 Gb/s. Numerical simulations show that the novel scheme can effectively mitigate the patterning effect in SOAs via shortening the rising/falling transition times. The high quality of the output signal (Q > 6) are numerically evaluated for both AND/XOR gates. (c) 2012 Elsevier B.V. All rights reserved.
