“…Illustrated in Figure 1a [7][8][9], the generation of the carrier reservoir (CR) layer adjacent to the active region (AR) in CR-SOAs is outlined. In a manner analogous to quantum dot (QD)-SOAs (See Figure 1b) [19,20], CR-SOAs exploit the concept of a "carrier reservoir" to augment their operational speed, albeit through a distinct physical mechanism.…”

“…As the bias current intensifies, the quasi-Fermi level progresses beyond the AR band edge. Consequently, the CR becomes infused with carriers, allowing it to promptly supply the AR-depleted by an input optical signal-with carriers during a transition time estimated to be between 5 and 10 ps [7][8][9]. The dominance of this ultrafast transition governs the gain dynamics, causing the CR-SOA to exhibit an equally swift temporal gain and phase response, mirroring that of the QD-SOA.…”

“…The XOR gate configuration, as depicted in Figure 2 [8,18], utilizing CR-SOAs-MZI, operates by launching two input data streams, denoted as A and B, from ports 1 and 2 of the CR-SOA-MZI1, respectively, via wavelength selective couplers (WSCs). Simultaneously, a continuous wave (CW) beam is introduced into port 3, where a 3-dB optical coupler (OC) evenly divides it into two identical copies.…”

“…This marks a significant departure from conventional electronic methods. CR-SOAs present a promising platform for achieving ultrafast, parallel, and all-optical computation due to their unique carrier reservoir dynamics [7][8][9]. On the other hand, the MZI's advantages lie in its ability to perform all-optical signal processing, high sensitivity, interference control, versatility, compact design, low power consumption, capability for phase modulation and demodulation, and overall stability in various applications [10,11].…”

This research explores the forefront of all-optical data processing systems through the utilization of carrier reservoir semiconductor optical amplifiers (CR-SOAs). Recent advancements have showcased the successful design and implementation of CR-SOA-based combinational systems, incorporating pivotal elements like half adders, half subtractors, digital-to-analog converters, latches, header recognition, and header processors. These breakthroughs signify a significant stride towards the realization of faster and more efficient optical logic systems. This study delves into the distinctive characteristics of CR-SOA-based Mach–Zehnder interferometer (MZI) functioning as an XOR gate, emphasizing their transformative potential in information processing. By integrating them into the architecture of an all-optical 4-bit parity generator and checker, the research underscores the practicality of CR-SOA technology in all-optical processing, offering unprecedented speeds and facilitating enhanced data processing capabilities at a remarkable speed of 120 Gb/s return-to-zero pulses. In evaluating the performance of the proposed scheme, the research employs the quality factor metric. This assessment not only yields quantitative insights into the efficacy of CR-SOA-based logic systems but also establishes a critical benchmark for their practical implementation. The study further explores the impact of key data signals and CR-SOA parameters on this metric. The outcomes demonstrate the ability of the CR-SOA-based MZI to cascade and form more intricate logic circuits, thereby highlighting the versatility and potential of this innovative approach in advancing the landscape of all-optical data processing.

In this generation, high-speed communication has very demanding. In this respect, optical communication plays a crucial role in meeting the goal of high-speed communication. With the increasing demands of high-speed communication, huge data processing is also needed. Therefore, we have proposed a design of XOR and XNOR gates using five reflective semiconductor optical amplifiers (RSOA). Our proposed gates are dibit logic-based. To increase the reliability of the devise, we have incorporated this logic scheme. Here, we consider the logic state ‘0’ for the absence of pulse and logic state ‘1’ for the presence of pulse. The dibit logic ‘0 1’ and ‘1 0’ are similar as ‘0’ and ‘1’ in digtal states, respectively. To check its practical feasibility, we have simulated the proposed design in Matlabsoftware and also quality factor, contrast, and extinction ratios are calculated for this design.
