Binary increment operation using CRSOA-MZI switches

In this work, we study the possibility of implementing binary incremental operations utilizing Mach-Zehnder Interferometers (MZIs) and carrier-reservoir semiconductor optical amplifiers (CR-SOAs). The proposed structure is a 4-bit binary incrementor circuit, designed to increment binary numbers through controlled phase shifts in the MZI combined with the amplification properties of CR-SOAs. The circuit makes use of the MZI's interference characteristics to provide logical outputs, while the CR-SOA offers fast switching at low power consumption. The binary incrementor circuit finds use in memory addressing units, real-time data processing systems in all-optical networks, and optical processors for arithmetic tasks. We have demonstrated the feasibility of this architecture for high-speed, all-optical computing by theoretically designing the circuit and verifying its functionality through MATLAB simulations. An advantage of our design is its scalability: the 4-bit binary incrementor can be readily extended to an n-bit incrementor due to its symmetric design.
