摘要：
A color filter incorporating a submicrometer cascaded grating was proposed. The device was analyzed by the rigorous coupled-wave analysis (RCWA) and consisted of three parts: a substrate, a ZnS grating and an Al grating. Three different devices with the full width at half-maximum (FWHM) of similar to 100 nm and the peak transmission of more than 70% are designed based on the transmission characteristics under different structural parameters. Compared to the previous color filters incorporating a grating, the numerical results show that the transmission efficiency increases of more than 13% and the overlap of the tricolor output spectra decreases effectively.
