Abstract

An optical device for forming a distribution of a three-dimensional light field comprises: an array of individually addressable unit cells; each unit cell in the array of unit cells comprising a stack including: at least one electrode; and a resonance defining layer, comprising at least a phase change material, PCM, layer, wherein the resonance defining layer is patterned to define a geometric structure dimensioned for defining a wavelength-dependent in-plane resonance of an electromagnetic wave; wherein the at least one electrode causes a phase change of the phase change material based on receiving a control signal to alter a wavelength-dependency of resonance in the resonance defining layer for controlling the optical property of the unit cell; wherein unit cells in the array of unit cells are separated such that the PCM layer of a unit cell is separated from the PCM layer in an adjacent unit cell.
