Original Abstract Submitted

Light emitting diodes with regrown semiconductor layers and methods of manufacture are described. In an embodiment, a light emitting diode includes a base structure including a first cladding layer doped with a first dopant type (e.g. n-type) and step surface. A mesa pillar including an active layer protrudes from the step surface, and a regrown second cladding layer doped with a second dopant type (e.g. p-type) is in direct contact with and spans a bottom surface and sidewalls of the mesa pillar and the step surface.
