1. A resonant reflector for an optoelectronic device tuned to a wavelength, the resonant reflector comprising:

  • a first material layer having a thickness of an odd multiple of a quarter of the wavelength and also having a first refractive index, the first material layer having one or more patterned regions that extend down into the first material layer thus reducing the thickness of the first material layer in the one or more patterned regions, selected patterned regions being at least partially filled with a second material having a second refractive index, the first refractive index being less than the second refractive index, the second material having a thickness of an odd multiple of a quarter the wavelength; and

    a third layer positioned immediately adjacent the first material layer, the third layer having a third refractive index that is greater than the first refractive index.
