In presented work we propose an analogous device using antimony selenide as the PCM. The geometric design of the metasurface nanostructures was optimized using the SHGO algorithm to maximize mode contrast upon phase transitions of the material. Numerical simulations were conducted to analyze the output distribution as a function of the nanostructure array state and to determine the achievable value range for weight implementation. The results demonstrate the potential of this approach for future development of scalable photonic tensor cores.
