1. A light emitting diode (LED), comprising:

  • a base LED structure comprising;

    a first doped layer with an associated first contact;

    a second doped layer;

    an active region between said first and second doped layers;

    a current confinement layer positioned adjacent to said second doped layer and axially aligned with said first contact, said current confinement layer including a first face that faces said first contact, a second face that is opposite said first face and at least one sidewall that extends between said first face and said second face;

    a second contact on said second doped layer; and

    a roughened surface of said light emitting diode;

    wherein said second contact extends onto said second face of said current confinement layer that is opposite said first face.
