Microactivity LED with photon recycling

摘要

A microcavity LED (10) with photon recycling including a substrate (12) having at least one layer (14) of material positioned thereon, and a first cladding layer (18), a second cladding layer (22) and an active region (16) sandwiched therebetween forming a mesa (24) on the layer (14) of material. The mesa (24) has generally vertical sides (28) and an upper surface (26) with an electrically conductive and light reflective system (32) positioned on the vertical sides (28) of the mesa (24) and partially covering the upper surface (26) to form a first electrical contact (32) for the LED (10), the electrically conductive and light reflective system (32) defining a centrally located light emitting opening (34) on the surface (26) of the mesa (24), the mesa (24) having a diametric dimension of the surface (26) greater than one time larger than a diametric dimension of the opening (34). <IMAGE>
