Waveguiding via Transformation Optics

Maxim Elizarov, Andrea Fratalocchi

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We demonstrate that it is possible to surpass current limitations of nanophotonics and plasmonics by designing an artificial material which can emulate user-defined spatial refractive index distribution. The effective optical property of the material is engineered through the deformation of reflective substrate via transformation optics approach. We provide one of possible applications - subwavelength optical waveguide coupler device based on this technique.
