    Abstract: Techniques and mechanisms for a micro-LED (“uLED”) structure to facilitate efficient communication of an optical signal. In an embodiment, a columnar “nanopost” uLED structure comprises contiguous bodies of respective semiconductor materials, including a first body of a doped semiconductor material. The first body forms a pyramidal structure, wherein one or more others of the contiguous bodies are arranged on the first body in a vertically stacked configuration. More particularly, a second body of an undoped semiconductor material is to provide a quantum well of the uLED structure, wherein the second body does not cover or otherwise extend along vertical sidewall structures of the first body. In another embodiment, the pyramidal structure, in combination with the vertically stacked arrangement of semiconductor bodies, facilitates efficient communication of narrowly columnated optical signal by mitigating optical signal communication via vertical sides of the uLED structure.

    Abstract: Emissive display devices having LED sources with super-lambertian radiation patterns. An exemplary emission source may have a half-emission-cone-angle of less than 40°. A system, such as an augmented reality display system, employing such an emissive display device may display a reduction in power of up to three times relative to LED sources with a lambertian radiation pattern. In some systems, such as augmented reality display systems, the optical path down stream of such an emissive display device may be simplified and/or dimensionally scaled, and/or manufactured to lower tolerances. For example, a discrete collimating lens may be eliminated from the optical path of such an emissive display device.
