Abstract

Solid state lighting (“SSL”) devices with cellular arrays and associated methods of manufacturing are disclosed herein. In one embodiment, a light emitting diode includes a semiconductor material having a first surface and a second surface opposite the first surface. The semiconductor material has an aperture extending into the semiconductor material from the first surface. The light emitting diode also includes an active region in direct contact with the semiconductor material, and at least a portion of the active region is in the aperture of the semiconductor material.
