We investigate on novel structures to trap, confine, and manipulate the propagation of light, taking from transformation optics and the inverse scattering problem we search for suitable refractive index mappings to achieve light trapping, beam conversion, secon harmonic generation, etc. The resulting mappings are develop keeping in mind the [meta] materials limitations, thus enabling a new array of micro-light technologies.
