Abstract:
A method for fabricating a semiconductor laser screen comprising:epitaxially growing an etch stop layer of (Ga1âˆ’xAlx)yIn1âˆ’yP upon a sacrificial substrate; epitaxially growing a multi quantum well active gain region on the etch stop layer, said epitaxial growth of the multi quantum well active gain region comprising epitaxially growing a plurality of gain regions of GaInP separated by barrier layers of (AlxGa1âˆ’x)InP; epitaxially growing an output mirror comprised of a plurality of alternating layers of a first Ga1âˆ’xAlxAs composition and a second Ga1âˆ’xAlxAs composition on the multi quantum well active gain region; affixing a supporting carrier to the output mirror; removing the sacrificial substrate; and depositing a metallic mirror on the etch stop layer to thereby form the semiconductor laser screen having a laser cavity bounded by the output mirror and the metallic mirror.
