Manipulation of optical fields by micro- and nanostructured media has undergone millions of years of evolution. The structural color identified in some animals is one example that permits the study of the role of light in ecosystems and its evolution history. To transfer this natural concept of subwavelength-structured optical interfaces to provide state-of-the-art optical systems, diffractive optics’ essential role must be thoroughly understood. Diffractive optics is widely recognized as an important growth area in modern optics. The successful insight into the field of optical engineering and photonics offered by diffractive optics proves tremendous advantages over conventional bulk optics. The increasing demands and desire to improve telecommunication, optical computing, consumer electronics, laser material processing, biomedical sciences, and manipulation of nano-objects through micro-optical systems have driven the advance in diffractive optics, which creates a large number of new avenues in optical research and new directions in nanophotonics research.
