This paper investigates the submicron scale color filter design in the high-definition computer-generated hologram (HD-CGH). It is addressed that single pixel structural coloration is essential for full-color wide-viewing angle HD-CGH because the conventional RGB color stripe filter degrades HD-CGH image quality due to low misalignment tolerance. Considering that a submicron scale slit or hole with metallic mirror sidewalls can operate as a single pixel color filter. We propose a design of single pixel RGB plasmonic color filter (PCF) and present the feasibility of applying the proposed single pixel RGB PCF to high-definition HD-CGHs. Based on the RGB PCF platform, a 1.1 μm× 1.1 μm RGB PCF is designed and the corresponding optical characteristics of the full-color HD-CGH are analyzed.
