Abstract

The performances of all-optical logic gates AND, OR, XOR, NOT based on quantum dot semiconductor optical amplifier (QD SOA) devices have been simulated. The saturation power, optical gain and optical phase response of a QD SOA has been analyzed numerically using a rate equation model of quantum dots embedded in a wetting layer. The calculated response is used to model the performance of the logic gates. Impacts of injection current and the input signal power on system quality factor have been studied. For the parameters used in this paper, all-optical logic gates using QD-SOA is capable of operating at speeds of ~ 250Gb/s.
