Abstract
We propose an ultrafast all optical NOR gate for 160 Gb/s return-to-zero Gaussian data signals using a single quantum-dot semiconductor optical amplifier (QD-SOA) and optical filter (OF). By conducting numerical simulations, we investigate and evaluate the impacts of probe wavelength and power of the involved signals on the extinction ratio (ER) and Q2-factor. Results show that the proposed NOR gate can be achieved both with logical correctness and high quality when the specified conditions are satisfied.
