Modern-day technologies like optical computing, integrated photonics, and digital holography require light signals to be manipulated in three dimensions. To achieve this, it is necessary to be able to shape and guide the flow of light according to its desired application. Given that light flow within a medium is governed by the refractive index, specific tailoring of the refractive index is needed to realize control of the light path within the medium.
