Diffractive optics is based on the phenomenon of light diffraction induced by wavelength-scale surface structures. The structures can affect either the phase or amplitude of the incident light or on both. Diffractive optics can be applied in beam splitters, diffractive lenses, beam shaping, etc. Nanophotonics involves the interaction of light with structures with dimensions smaller than the used wavelength. In our case, we divide this into two categories: metamaterials and plasmonic structures. Metamaterials can be used, for example, in polarizers and as a replacement for diffractive optics. Plasmonic structures are typically used in enhancing light fields, e.g., in Raman and fluorescent spectroscopy.

We offer rigorous electromagnetic theory-based design services for diffractive optics and nanophotonic components.
