Abstract
We present efficient design of subwavelength diffractive optical elements (DOEs) based on finite-difference time-domain (FDTD) method and optimization by genetic algorithm (GA). Using the GA-FDTD method, we successfully optimize the structure of polarizing beam splitter (PBS) and focusing lens. We also show design of hybrid functional DOEs that double as PBS and lens.
