ABSTRACT:
Light emitting and waveguide devices with single-sided photonic bandgaps are provided. The light emitting device is formed from a heavily doped silicon (Si) bottom electrode, and a Si-containing dielectric layer embedded Si nanoparticles overlying the bottom electrode. A transparent indium tin oxide (ITO) top electrode overlies the Si-containing dielectric layer, and a photonic bandgap (PBG) Bragg reflector underlies the Si bottom electrode. The PBG Bragg reflector includes at least one periodic bi-layer of films with different refractive indexes. The single-sided photonic bandgap planar waveguide interface is formed from a planar waveguide and a PBG Bragg reflector underlying the planar waveguide.
