Fabrication Methods for Photonic Crystal Surface Emitting Lasers (PCSELs) by Molecular Beam Epitaxy

Molecular Beam Epitaxy (MBE) is used for fabrication of Photonic Crystal Surface Emitting Lasers (PCSELs). Two methods of PCSEL fabrication are explored and compared: epitaxial regrowth and non-regrowth. Optically pumped and electrically injected devices are demonstrated by epitaxial regrowth.
