Abstract
In the modern era, high-speed signal communication and computation increase the optical reliability. Therefore, optics are a powerful candidate for implementation in different logic gates, combinational circuits, devices, optical computers, etc. The design of all-optical frequency encoded dibit-based half-subtractor is devised in this communication. Some papers are focus on the advantage of the precision of dibit logic by carrying out logic operations on dibit representation technique. This devised dibit-based design operates with a high speed as well as reduces the bit error problem by increasing the high signal-to-noise ratio. Frequency encoding is the most reliable encoding technique because of its unaltered nature in reflection, refraction, absorption when propagates in long-range. In this devised design, add/drop multiplexer and reflected semiconductor optical amplifier are used to fulfill the purpose of optical switches. This design consumes low power. The operation of the devised design is verified through simulation using MATLAB Simulink (R2018a) software.
