The adder is a highly fundamental part of the central processing unit. The carry lookahead adder (CLA) has become the fastest adder used in digital circuits. For high-speed operations, optical computing has become an essential research field. In this manuscript, a microring resonator (MRR)-based all-optical (AO) CLA is proposed and analyzed. The MRR-based AO design is capable of getting a higher operational speed to fulfill the demands of end users. The Z domain's mathematical model of the CLA is developed using the unit delay signal processing method. The numerical simulations validate the proposed circuit's operational speed of close to 260 Gbps. The parameters for this design are chosen optimally to enable it to be effectively implemented for optical computations.

“…By phase encoding using four wave mixing (FWM) in semiconductor optical amplifier (SOA), half addition and half subtraction are performed to implement superfast arithmetic logic unit (ALU) [7]. All-optical full adder with ER and Q-factor of 11.7 dB and 12.5, is implemented using QD-SOA based mach-zehnder interferometer as a basic building block to perform other signal processing function [8]. Phase encoding scheme has been exploited to perform half addition and half subtraction to implemented digital comparator [9].…”

By exploiting the phenomena of optical switching, different logic functions for all-optical digital signal processing has been projected. This paper presents the application of optical switching to design of all-optical half adder and half subtractor by Mach-Zehnder interferometer. All-Optical half adder and half subtractor are designed with the optimized structure of 2 × 2 Mach-Zehnder interferometer switch by electro-optic effect in lithium niobate. Numerical simulations of the proposed structure have been conducted to verify the suitability of the designed structure using Opti-BPM software. The implementation of proposed structures is simulated in MATLAB software along with the mathematical description. It is interesting to analyze that the proposed structures are useful to generate combinational and sequential logic circuits in high-speed optical signal processing and switching network.

“…A winner of the Nobel Prize, Serge Haroche, has presented an interesting non-demolition method for measuring Wigner function in a quantum cavity [12]. On the other hand, the Mach-Zehnder interferometry is applied to Bell's inequality [22,23], electronic Mach-Zehnder interferometer (MZI) [24], single and two photon interferometry [25,26], production and observation of Greenberger-Horne-Zeilinger entanglement [27], and optical amplification [28,29].…”

Recently, manipulation and measurement of quantum states, especially in quantum cavities, have attracted the attention of many researchers in different fields, such as quantum optics, quantum information, and quantum computation. In this paper, a non-demolition method for the measurement of squeezing parameter via atomic Mach-Zehnder interferometer is presented. An experimental setup was also proposed which included two quantum cavities, in different arms of an atomic Mach-Zehnder interferometer. Each quantum cavity was settled between two classical cavities. Quantum cavities contained entangled states with arbitrary squeezed photons. It is shown that the outgoing atomic states of Mach-Zehnder interferometer carry on the properties and situation of quantum states of the cavities. The squeezing parameter of photonic state for one of the cavities is obtained by the detection of excited and non-excited probabilities of Mach-Zehnder interferometer's outgoing ports, for a train of incoming two-level Rydberg atoms.
