  • a structure including a light emitting region disposed between an n-type region and a p-type region; and

    a reflector disposed on at least a portion of a bottom surface of the structure, wherein;

    a plurality of holes in the structure are formed in a first region of the structure corresponding to a first portion of the light emitting region;

    a plurality of second regions of the structure, each second region corresponding to a second portion of the light emitting region, are free of holes;

    each of the second regions is surrounded by the first region;

    in areas of the structure disposed between individual holes, a nonconductive material is disposed between the light emitting region and the reflector; and

    the device is configured such that when forward biased, current is injected in the second regions and at least a portion of the first region is substantially free of current.
