<p>Reversible logic has gained attention as an important computing model with applications in fields such as quantum computing, optical computing, communication, and nanotechnology. As technology advances, reversible logic finds its importance as a key approach to modern challenges. This type of computing not only aligns with the fundamental laws of physics but also holds the potential for zero power dissipation by preventing entropy loss during computation. A key area within optical computation is the multi-valued logic (MVL) system, which operates with more than just the binary true or false values by introducing intermediate states. MVL allows more efficient handling of information. Among the MVL systems, trinary logic (three-value system) is particularly promising for optical applications, as it is better suited for computation compared to the quadruple-valued logic system. In this context, the paper proposes an Optical Trinary Toffoli Gate utilizing a Spatial Light Modulator (SLM) and Savart Plate for implementation, along with its potential uses in computation.</p>
