摘要:
A micro-light emitting diode (LED) includes an epitaxial structure having a mesa and a top portion on the mesa. The epitaxial structure further includes quantum wells within the mesa configured to emit light, claddings surrounding the quantum wells, and a light emitting surface on a side opposite the mesa and top portion. A reflective contact is on the top portion of the epitaxial structure. Light emitted from the quantum wells are transmitted through the mesa and the top portion in first directions, and reflected by the reflective contact back through the top portion and the mesa in second directions toward the light emitting surface. The top portion allows the quantum wells to be positioned at a parabola focal point of the mesa without limiting cladding thickness.
