In this paper, the semiconductor optical amplifier (SOA) is used with a Mach-Zehnder interferometer (MZI) forming an SOA-MZI structure which is used to perform the logic gates OR, and NOT. It is simulated at 10 Gbps, 20 Gbps, and 40 Gbps to extract simple design rules. Two binary input data signals are simulated at several bitrate 10 Gbps, 20 Gbps, and 40 Gbps. It is demonstrated that high data rate can be achieved with a specific injection current in SOA. SOAs required low injection current, which leads to a low value on the total power consumption of the gate. In addition, this work includes the study of the effect of the bit rate on the received power, minimum bit error rate (BER), and maximum quality factor (Q-factor). The logical output of the gate has an extinction ratio of more than 10 dB with good eye opening. The output of the OR, NOT gates shows error-free operation at different bit rate with a clear eye opening. General TermsOptical amplifier, MZI, optical logic gates.

“…All-optical gates constitute key building units for the development of lightwave broadband communications networks through the execution of signal processing functionalities without problematic optoelectronic conversions at the photonic nodes [1]. In particular the AND gate is indispensable for achieving this goal as it is involved in the accomplishment of numerous tasks in the optical domain both in fundamental and system-oriented level, such as buffering [2], address comparison [3], add-drop multiplexing [4], packet clock and data recovery [5], packet header and payload separation [6], binary pattern recognition [7], binary counting [8], analog-to-digital conversion [9], digital encoding and comparison [10], data regeneration [11], waveform sampling [12], half addition [13], multiplication [14], construction of other logic gates [15] and of combinational logic circuits [16].…”

Abstract-The feasibility of realizing an all-optical AND gate for 320 Gb/s return-to-zero data by incorporating quantum-dot semiconductor optical amplifiers (QD-SOAs) in a Mach-Zehnder interferometer (MZI) is theoretically investigated and demonstrated. The proposed scheme employs the QD-SOA-based MZI in a configuration where the QD-SOA in one MZI arm is subject to the first data sequence, the QD-SOA in the other MZI arm receives no such input but is constantly held in the small signal gain regime, and the second data stream is inserted from the common MZI port acting as enabling or disabling signal. Compared to other approaches adopted for the same purpose this implementation is more general, direct, flexible and affordable as only one strong data signal is required to control switching. By conducting numerical simulation the impact of the critical parameters on the Q-factor is thoroughly assessed. The obtained results are interpreted with the help of a complete characterization of the QD-SOA response to an ultrafast data pulse stream. This allows to specify the requirements that the critical parameters must satisfy to achieve acceptable performance. The extracted design rules are technologically realistic and ensure AND operation both with logical correctness and high quality. The outcome of the numerical treatment extends the range of Boolean functions executed with the QD-SOA-MZI module at sub-Tb/s data rates.

“…Proposals based on polarization based logic implementation have some drawbacks as the state of polarization may change at the reflecting or refracting points along the transmission or propagation path [3,4]. Compared with the nonlinearity of optical fiber, the semiconductor optical amplifier (SOA)-based all-optical signal processing has demonstrated great potential in terms of low power consumption, fast switching time, and optical integration [6][7][8]. Semiconductor optical amplifier (SOA) is a very attractive non-linear device, but SOA based proposals using interferometric configurations including two or more devices need accurate control and stabilization schemes [9,10].…”

We demonstrate an optical gate architecture using a single SOA to perform AND, OR and NOT logic functions. Simple reconfigurable all-optical logic operations are implemented using RZ modulated signals at 40 Gb/s. Contrast ratio and extinction ratio values have been analysed for the different types of logic gates. Maximum extinction ratio and contrast ratio achieved are 19dB and 17.2 dB respectively. Simple structure and potential for integration makes this architecture an interesting approach in photonic computing and optical signal processing.
