Abstract
A far-field characteristic of light emitted by a micro light emitting diode (μLED) such as a beam shape, a beam orientation, a beam focusing, or a beam polarization is controlled by a metasurface of nanostructures formed on the μLED. The metasurface is characterized or defined by a far-field objective function for the emitted light, selection of a nanostructure shape, and application of one or more fabrication constraints to shape parameters for the selected nanostructure shape. A number and a location of the nanostructures is determined employing an adjoint simulation technique, and the shape parameters for the nanostructure are tuned employing a shape optimization technique.
