Summary:

We propose an all-optical AND gate using an optical hard limiter (OHL). The OHL is based on the Mach- Zehnder interferometer (MZI) with quantum-dot semiconductor optical amplifiers (QD-SOAs). The proposed operation utilizes self-phase modulation (SPM), which is one of several nonlinear optical phenomena in QD-SOA. We determine the output signal waveform and extinction ratio (ER) by numerical analysis. Additionally, we show that the proposed AND gate is capable of operation at 840 Gbit/s.
