“…This capability is facilitated by the MZI's potential to operate in either the cross or bar state, rendering it an effective tool for switching within all-optical networks. 6 A 2x2 MZI configuration underpins this functionality, offering dynamic transitioning between the two operational tasks as dictated by the system's requirements.…”

We propose a dual-task, all-optical processor controlled by a Machine Learning-based digital optimizer. This innovative system compensates for signal impairments in Intensity Modulation/Direct Detection (IM/DD) and mitigates bandwidth limitations, reducing the need for power-hungry Digital Signal Processing (DSP). The synergy between the optical processor and digital optimizer, operating with the Tree-structured Parzen Estimator algorithm, forms a photonic Reservoir Computing approach that enhances signal performance and reach. This versatile system can function as an all-optical equalizer and chromatic dispersion compensation filter, outperforming traditional electrical counterparts. The proposed scheme, offers a cost-effective and efficient solution for next-generation access networks.

“…In [7], the SOA is implemented using cross-gain modulation (XGM) technique and the bit rate was 10 Gb/s. M. Islam and M Barsha in 2018 [8] showed that the MZI could be used as a switch when it is connected either on cross or bar state. They demonstrated that when MZI used as a switch, all optical logic gate networks will be implemented easily.…”

Conventional logic gates failed to process data at a high bit rate. Therefore, researchers began to study the design of these gates with optical technology, which is characterized by high bit rate data processing. The non-linear behavior is a drawback in semiconductor optical amplifier (SOA). This nonlinearity property of the SOA is used in this paper to implement the OR optical gates. Mach-Zander interferometer (MZI)-based structures are among the numerous of structures that are available to transform a modulation of phase into a modulation of intensity. These are widely used by electro-optic (EO), or thermo-optic (TO) impacts to create various applications like optical modulators, splitters, switches, etc. In this paper, the MZI is used as switches and the SOA is employed with cross-gain modulation (XGM) to implement the optical logic gate OR at a high bit rate of 250 Gbps. Several experimental results were performed on the proposed design of the OR gate until the optimum value of the injection current, which is 0.08 A, was obtained. This optimum value led to achieve the lowest BER, highest Quality factor, and lowest power consumption, which are 0, 60.7989, and 31.13×10-3, respectively. The experimental results of the proposed design outperformed those results obtained by other state-of-the-art designs.
