“…The phenomena of FWM occurs inside SOA when more than one light waves with different frequency inserted into it and as a result of FWM in SOA it will produce many idler signal light waves of different amplitudes, frequencies and phases based on the third order non linearity of it [10]- [14]. In case of FWM in SOA, if the three waves interact with one another, then two of them act as a pump waves and the other as probe generates different idler components with the unmodified inputs also are given by …”

“…This work enhanced the SOA-MZI based XOR logic gate whereby it only uses a train of pulses or CW beam as the control signal. Besides that, phase shifter is added to the circuit in order to shift the output signal for 900 because the signal travelling through the input acquires a phase change subjected to the cross phase modulation [6] . Two-photon absorption (TPA) is one of the nonlinear optical phenomenon absorption processes that occur when two photons are absorbed and excited from lower state to higher state.…”

Abstract. Two-photon absorption with high intensity pump beam occurs in a SOA depends on fast phase change of a weak probe signal. This work analysed optical XOR logic function using two-photon absorption induced fast phase change. A rate equation for SOA and both input data signals A and B with high intensity, configured in the form of MZI has also been proved. The model shows that XOR operation at 10 Gb/s with good signal to noise ratio is obtained with high input intensities. The result on the generation of XOR indicates that operations on 10 Gb/s with a high signal to noise ratio can easily be implemented. The average input power into the SOA is 20 dbm corresponding to the peak power of 5.5 dBm at 10 Gb/s when the width of the input pulse 3.6 ps. The short narrow pulse width is utilised in the study for stronger effect of two-photon absorption.

“…This phase preservation cannot be achieved using any of the other techniques that may be used for all-optical signal processing with SOA's and has huge potential for use in optical systems. One good example is the possibility to perform wavelength conversion and demultiplexing with Differential Phase-Shift Keying (DPSK) format data in all-optical networks [6,7].…”

Four-wave mixing was performed in a multi-quantum well semiconductor optical amplifier in order to demultiplex 2 ps pulses from 80 GHz to 10 GHz. The demultiplexed pulses were measured using frequency resolved optical gating. This technique allows for full characterization of the pulses in both the time and frequency domains. The measurements confirm that the four-wave mixing conjugate signal preserves the phase of the injected signal. Furthermore, in the time domain the influence of the pulse pedestals present on the injected probe pulses is significantly increased on the output four-wave mixing signals. This effect is attributed to the nonlinear suppression of the device gain.
