“…The extinction ratio of the input signals was assumed to be 10 dB. The parameter values were taken from the literature on other QD-SOA-based interferometric gates [19][20][21][22]. These are: In order to assess the performance of an optical logic design, the most important parameters are extinction ratio, amplitude modulation, quality factor, pseudo-eye diagram, and relative eye opening, which we will investigate.…”

This paper presents the simulation and design of an all-optical subtractor using a quantum-dot semiconductor optical amplifier Mach-Zehnder interferometer (QD-SOA MZI) structure consisting of two cascaded switches, the first of which produces the differential bit. Then the second switch produces the borrow bit by using the output of the first switch and the subtrahend data stream. Simulation results were obtained by solving the rate equations of the QD-SOA. The effects of QD-SOA length, peak power and current density have been investigated. The designed gate can operate at speeds of over 250 Gb/s. The simulation results demonstrate a high extinction ratio and a clear and wide-opening eye diagram.

“…A data-carrying signal A enters through a wavelength selective coupler (WSC) QD-SOA1, while a data-carrying signal B is inserted in the MZI and is split via the input 3 dB coupler C1 into a pair of identical parts, which travel separated along the QD-SOAs located in their path. Signal A should be at least an order of magnitude stronger than signal B [49]. These signals are discriminated by using different wavelengths, such that their detuning in the 1550 nm region is less than Figure 2.…”

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.
