“…The structure of the SOA in conjunction with the optical fiber is limited to the high-speed because of the phase recovery characteristics and the slower gain. Therefore, the MZI is the right choice to overcome the limitation of the high bit rates [15,16].…”

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.

“…The all-optical non-inverted parity generator and checker based on SOAs is shown in Figure 1. From the principle of the optical generator and checker circuit, we found that it can be composed of XOR [14][15][16] and XNOR [17,18] gate, the dotted line section, and the entire working in Figure 1 correspond to the parity generator and checker, respectively.…”

“…Due to the integration of potential and good non-linear characteristics of semiconductor optical amplifiers, people have a strong research interest. There are extensive studies in all-optical signal processing and all-optical calculations, such as switches, clocked flip-flops [13], logic gates [14][15][16][17][18], subtracter and adder [19][20][21][22], decoder/encoder [20,23], and comparator [23,24]. It can be seen from the research of various all-optical technologies that semiconductor optical amplifiers have broad application prospects in future optical communication systems.…”

An all-optical non-inverted parity generator and checker based on semiconductor optical amplifiers (SOAs) are proposed with four-wave mixing (FWM) and cross-gain modulation (XGM) non-linear effects. A 2-bit parity generator and checker using by exclusive NOR (XNOR) and exclusive OR (XOR) gates are implemented by first SOA and second SOA with 10 Gb/s return-to-zero (RZ) code, respectively. The parity and check bits are provided by adjusting the center wavelength of the tunable optical bandpass filter (TOBPF). A saturable absorber (SA) is used to reduce the negative effect of small signal clock (Clk) probe light to improve extinction ratio (ER) and optical signal-to-noise ratio (OSNR). For Pe and Ce (even parity bit and even check bit) without Clk probe light, ER and OSNR still maintain good performance because of the amplified effect of SOA. For Po (odd parity bit), ER and OSNR are improved to 1 dB difference for the original value. For Co (odd check bit), ER is deteriorated by 4 dB without SA, while OSNR is deteriorated by 12 dB. ER and OSNR are improved by about 2 dB for the original value with the SA. This design has the advantages of simple structure and great integration capability and low cost.
