1. A structure using integrated optical elements, comprising:

  • (a) a substrate;

    (b) a buffer layer grown on the substrate;

    (c) one or more patterned layers deposited on top of the buffer layer, wherein each of the patterned layers is comprised of a mask and materials filling holes in the mask; and

    (d) one or more active layers formed on or between the patterned layers;

    (e) wherein each patterned layer acts as a mirror, optical confinement layer, grating, wavelength selective element, beam shaping element or beam directing element for the active layers.
