Engineering the Phase Front of Light with Phase-Change Material Based Planar lenses
A novel hybrid planar lens is proposed to engineer the far-field focusing patterns. It consists of an array of slits which are filled with phase-change material Ge(2)Sb(2)Te(5) (GST). By varying the crystallization level of GST from 0% to 90%, the Fabry-Pérot resonance supported inside each slit can...
