| Abstract(in English) | We studied the polarization independent design of first-order transmission diffractive optical elements (DOEs) using optical simulation based on RCWA and computational optimization of SA method. To realize high diffraction efficiency and low polarization dependence, reduction of reflection at upper and bottom surfaces of a grating is important. So, by using the 2-layer structure of Ta_2O_5 and SiO_2, good design which satisfy the optical performance at broad wavelength band was obtained. Furthermore, in order to verify the effect of multi-layer structure, we fabricated the 2-layer DOE. Good optical performance considering high angle dispersion, and good agreement between experiment and simulation were obtained. |
