چکیده

Plasmonic gratings and nano-particle arrays in a metal-insulator-metal structures are fabricated on an erbium doped silicon nitride layer. This material system enables simple fabrication of the structure, since the active nitride layer can be directly grown on metal. Enhancement of collected emission of up to 12 is observed on resonance, while broad off-resonant enhancement is also present. The output polarization behavior of the gratings and nano-particle arrays is investigated and matched to plasmonic resonances, and the behavior of coupled modes as a function of inter-particle distance is also discussed.

Silicon Based Photonic Crystal Light Sources a Dissertation Submitted to the Department of Electrical Engineering and the Committee on Graduate Studies of Stanford University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy

Efficient light generation on silicon is desirable for a variety of applications because of its low fabrication cost relative to III/V semiconductors and because it will enable monolithic integration with electronic components on the same Si platform. We studied silicon-rich silicon nitride with emission in the visible and erbium-doped silicon nitride (Er:SiNx) with emission at 1540 nm. Both of...

Erbium-doped silicon nanocrystals in silicon/silicon nitride superlattice structures: Light emission and energy transfer

In this paper, we discuss optical emission, energy transfer and electroluminescence from a superlattice structure containing small ( 2nm diameter) amorphous silicon (Si) clusters coupled to erbium (Er) ions. The superlattice structure is fabricated by direct co-sputtering of thin ( 3–5nm) Er-doped siliconrich nitride/Si (Er:SRN/Si) layers subsequently annealed at different temperatures in order...

Parallel Transduction of Nanomechanical Motion Using Plasmonic Resonators

We demonstrate parallel transduction of thermally driven mechanical motion of an array of gold-coated silicon nitride nanomechanical beams, by using near-field confinement in plasmonic metal-insulator-metal resonators supported in the gap between the gold layers. The free-space optical readout, enabled by the plasmonic resonances, allows for addressing multiple mechanical resonators in a single...

In this paper, we present our main results on the structural and optical properties of light-emitting amorphous silicon nitride (SiNx) films fabricated by reactive magnetron cosputtering. In particular, we discuss the origin of the visible emission in amorphous silicon nitride films and investigate the optical emission properties of Erbium-doped amorphous silicon nitride (Er:SiNx). The mechanis...
