nano-optical devices can perform any passive optical function, including polarization filtering, phase retardation, spectral filtering, and emission management (e.g., lenses and beam splitters)

Spatial integration can be achieved by organizing different optical functions in an array structure through nanopattern repetition. Hybrid integration is achieved by adding a nano-optical layer(s) to the functional optical materials.

It is possible to optimize  the architecture of traditional multi-element and multi-technology optical circuits by utilizing the unique optical behavior of nano-optics. Seamless "self-integration" can be achieved by layering one on top of another to create overall optical effects

Through the appropriate combination of materials and structures, nano-optical devices can perform any passive optical function, including polarization filtering, phase retardation, spectral filtering, and emission management (e.g., lenses and beam splitters).  Various functions can be designed for free-space and wave-based applications.  Nano-optical devices can also be designed to operate in any wavelength range.  The basic method is applicable to UV, visible, and IR wavelengths with appropriate variations in structural dimensions and materials.  Furthermore, they can form the core of an optical system.  Practical applications of nano-optical devices require a complete optical system consisting of nano-patterned materials and adjacent materials including the optical substrate and thin film coatings. Nano-optical structures are defined as a combination of material and physical properties.
