1. A light emitting device comprising:

  • a stack of semiconductor layers defining a light-emitting pn junction; and

    a dielectric layer disposed over the stack of semiconductor layers, the dielectric layer having a refractive index substantially matching a refractive index of the stack of semiconductor layers, the dielectric layer having a principal surface distal from the stack of semiconductor layers, the distal principal surface including patterning, roughening, or texturing configured to promote extraction of light generated in the stack of semiconductor layers.
