In the field of optical communications, there is a growing demand for compact and high-performance optical logic gates that enable all-optical signal processing. Optical logic gates based on nonlinear optical effects require high optical intensity, which poses a challenge in terms of power reduction. To address this issue, optical logic gates using only linear media have been proposed. In this study, we perform optimal design of a half-adder optical logic device composed of linear media using the finite element method (FEM) and covariance matrix adaptation evolution strategy (CMA-ES). Furthermore, we investigate the design of an optical logic device that can be easily implemented as a mosaic-type structure by representing the design region with fine pixels based on the density method.
