A method according to the present invention for fabricating high light
extraction photonic devices comprising growing an epitaxial semiconductor
structure on a substrate and depositing a first mirror layer on the
epitaxial semiconductor structure such that the epitaxial semiconductor
structure is sandwiched between the first mirror layer and the substrate.
Flip-chip mounting the epitaxial semiconductor structure, with its first
mirror and substrate on a submount such that the epitaxial semiconductor
device structure is sandwiched between the submount and substrate. The
substrate is then removed from the epitaxial structure by introducing an
etch environment to the substrate. A second mirror layer is deposited on
the epitaxial semiconductor structure such that the epitaxial
semiconductor structure is sandwiched between the first and second mirror
layers. A device according to the present invention comprising a resonant
cavity light emitting diode (RCLED) mounted to a submount.
