“…So we exploited the attractive frequency encoding techniques for their advantageous aspects of unalternation of the signal even after reflection, refraction, and attenuation in long-haul communication networks 35 – 40 We use the optical signal of frequency “ν1” to encode the binary state “0” and frequency “ν2” to encode the binary state “1.” The basic block diagram of Toffoli gate is shown in Fig. 1, and the frequency-encoded data-based truth table of Toffoli logic gate is shown in Table 1.…”

Bit-error detection and correction is a very important part of a data communication network. In this article, we propose an optical approach to designing an error detection and correction circuit using Hamming code-based frequency encoded binary data and Toffoli gates.Here, the Toffoli gates are made of semiconductor optical amplifiers (SOAs) that work based on the nonlinear polarization rotation property. The characteristics of SOA, including very fast switching action (about 0.01 ns), low power consumption, frequency independent crosspolarization gain in the C-band, cascading property, etc., make the scheme attractive. The frequency encoded data-based proposed scheme will be effective for WDM communication networks. MATLAB simulation results testify to the feasibility of the proposed scheme.

“…To break through the bottleneck of the circuit implement method, some photoelectric hybrid JK flip-flops based on two-photon scattering in Mach-Zehnder interferometers, polarization switch or micro-ring resonators have been reported [2][3][4] . Meanwhile, all-optical flip-flop, as one of candidate basic units of optical memory, buffering, packet-switched network, shift registers, counters and RAM, has become a hot spot [5][6][7][8][9] .…”

In this paper, we propose an all optical JK flip-flop system consisting of three vertical-cavity surface-emitting lasers with embedded saturable absorber (VCSEL-SAs) is proposed and numerically simulated. Also, the effects of injection intensity, delay and noise on the JK flip-flop are numerically analyzed. The results show that, based on the spiking dynamics of excited VCSEL-SA, the proposed alloptical JK flip-flop model can perform all the fundamental functions of conventional JK flip-flop under suitable bias current, injection intensity and perturbation delay between two trigger signals. Moreover, the noise has a little effect on the performance of JK flip-flop, but the proposed system has good robustness to the noise. The results provide a feasibility for the application of VCSEL-SA devices in the future ultrafast neuromorphic computing systems.

“…Flip-flop is the basic element for designing any types of counter. Over a period of time various attempts have been made by many research groups to design optical flip flops, synchronous and asynchronous counters [1][2][3][4][5][6][7][8][9][10][11]. Optical flip-flop using two polarization switches has been demonstrated by Y. Liu [1 ]; Zhang et al demonstrated the working of Multi -state flip flop using ring laser [2] ]; S. Mandal et al described a method to design AOFF using PSW [3,4 ]; T. Chattopadhyay et al…”

In digital signal processing and data communication system in optical domain it is paramount important to count the pulse number of any device or processor and hence optical counter for fast counting. In this letter the authors propose a new method to implement an all-optical 3- bit asynchronous binary counter comprising all-optical T flip flops which works based on the polarization switching characteristics of SOA, and frequency encoded data have been used for communication purpose. Use of Frequency encoding technique in the proposed scheme makes it attractive and effective one in various aspects in wave division multiplexing based communication network. Simulation aided results support the practicability of the proposed scheme.
