A wide variety of micro and nano-structured optical elements have been developed. Among other things, optical elements with subwavelength structure surfaces are moving on the advanced stage for practical use. A camera lens with antireflective structured surface and an achromatic birefringent wave-plate have been fabricated by plastic molding process. Form-birefringent micro-reader array is used for a polarization imaging camera system. Recent research-and-developments on subwavelength structured optical elements are oriented to practical applications and process technologies for manufacturing. In this paper the current situation of the subwavelength structured optical elements have been summarized and subjects of developments are discussed from the viewpoint of practical applications.
