Abstract
An optical emitter includes micro-structure phosphor coating on a light-emitting diode die mounted on a package substrate. The micro-structures are transferred onto a micro-structure phosphor coating precursor by patterning and curing the precursor or by curing the precursor through a mold. The micro-structures are half spheroids, three-sided pyramids, or six-sided pyramids.
