“…The coupling equation outlined in the reference [25,26] demonstrates a relative phase of between the input signal at the input port and the signal coupled into the ring. Likewise, the signal coupled into the drop and through ports, where both are acquired a phase of 2 ⁄ regarding the signal in the input port.…”

A dark-bright soliton conversion is used to perform the two arithmetic logic unit(ALU) operations namely adder and subtractor operations. The advantage of the system such as power stability, non-dispersion and the dark-bright soliton phase conversion control can be obtained. The input source into the circuit is the bright soliton pulse, with the pulse width of 35 ps, the peak power at 1.55 µm is 1 mW. By using the dark-bright soliton conversion pair, the generated logic bits can be controlled, and the secure bits can be achieved. The simulation results show the output signal with a minimum loss of only 0.1% with respect to a low input power of 1 mW, and ultra-fast response time of about 0.30 ps can be achieved. It gives the ultra-high bandwidth of more than 40 Gbits-1. The circuit composes 6 microring resonators made of InGaAsP/InP material with smaller ring radii of 1.5 µm, and the total physical scale of the circuit less than 100 2 .

“…OMRR based optical switch is a suitable choice to develop various sequential and combinational circuits. Available literature provides different techniques to implement all-optical J-K flip flop [14,15], D flip flop [16][17][18][19][20][21][22] and S-R flip-flop with ring resonators [23].

Optical switches play a key role in the field of high-speed optical fiber communication and signal processing. Present work shows the design and implementation of D-flip flop and a two-bit optical counter using optical micro ring resonator (OMRR). The design of the proposed model is developed by considering nonlinear material-based resonators. Here, three OMRR based optical switches are used to design the D-flip flop circuit thereafter two-bit optical counter is implemented using the modeled D-flip flop. The mathematical model of the D-flip flop circuit is provided in the Z-domain by unit delay signal processing approach. The effectiveness of the proposed D flip flop and two-bit down counter circuit is described in the present work. The accuracy and feasibility of the circuits are determined by estimating various performance parameters during simulation.

“…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.
