Light emission at 1.54 mu m from an Er-doped amorphous silicon nitride layer coupled to photonic crystal resonators and plamonic arrays is studied. We observe the cavity resonances at cryogenic and room temperatures and under varying optical pump powers. The results demonstrate that small mode volume, high quality factor resonators enhance Er absorption rates dramatically at the cavity resonance. Photonic crystal cavity resonances exhibit linewidth narrowing with pump power at cryogenic temperatures, signifying absorption bleaching and partial inversion of the Er ions. In addition, we fabricate periodic metal-insulator-metal plasmonic structures with a simple bottom-up fabrication technique. We observe a factor of 10 increase of Er emission coupled to plasmonic structures.

Dielectric matrix influence on the photoluminescence properties of silicon nanocrystals Ferraioli, L.; Cazzanelli, M.; Daldosso, N.; Mulloni, V.; Bellutti, P.; Yerci, Selçuk; Turan, Raşit; Mikhaylov, A.n.; Tetelbaum, D.ı.; Pavesi, L. (null; 2006-12-01) Photoluminescence properties of silicon nanocrystals embedded in five different oxide matrices are analyzed. Samples are silicon rich oxide and oxynitride produced by PECVD and ion implantation and crystalline and amorphous aluminum oxide implanted with silicon.
Linewidth narrowing and purcell enhancement in photonic crystal cavities on an Er-doped silicon nitride platform Gong, Yiyang; Makarova, Maria; Yerci, Selçuk; Li, Rui; Negro, Luca Dal; Vučković, Jelena (null; 2010-12-01) Light emission from Er-doped amorphous silicon nitride coupled to photonic crystal resonators is studied. The results demonstrate Purcell enhanced Er absorption and linewidth narrowing of the cavity resonance with increasing pump power.
Linewidth narrowing and Purcell enhancement in photonic crystal cavities on an Er-doped silicon nitride platform Gong, Yiyang; Makarova, Maria; Yerci, Selcuk; Li, Rui; Stevens, Martin J.; BAEK, Burm; Yerci, Selçuk; Hadfield, Robert H.; Dorenbos, Sander N.; ZWİLLER, Val; Vuckovic, Jelena; Dal Negro, Luca (2010-02-01) Light emission at 1.54 mu m from an Er-doped amorphous silicon nitride layer coupled to photonic crystal resonators at cryogenic and room temperatures and under varying optical pump powers has been studied. The results demonstrate that small mode volume, high quality factor resonators enhance Er absorption and emission rates at the cavity resonance. Time resolved measurements give 11- to 17-fold Purcell enhancement of spontaneous emission at cryogenic temperatures, and 2.4-fold enhancement at room temperatu...
STRUCTURAL STABILITY AND ENERGETICS OF C, SI, AND GE MICROCLUSTERS - EMPIRICAL MANY-BODY POTENTIAL-ENERGY FUNCTION CALCULATION Erkoç, Şakir (Springer Science and Business Media LLC, 1991-01-01) The structural stability and energetics of carbon, silicon, and germanium microclusters containing 3-7 atoms have been investigated by using a recently developed empirical many-body potential energy function (PEF), which comprises two- and three-body atomic interactions. The PEF satisfies both bulk cohesive energy per atom and bulk stability exactly. It has been found that the most stable C3-4 microclusters are linear with D-infinity-h symmetry but C5-7 microclusters are planar with D(nh) symmetry. Silic...
Segregation formation, thermal and electronic properties of ternary cubic CdZnTe clusters: MD simulations and DFT calculations KURBAN, MUSTAFA; Erkoç, Şakir (Elsevier BV, 2017-04-01) Surface and core formation, thermal and electronic properties of ternary cubic CdZnTe clusters are investigated by using classical molecular dynamics (MD) simulations and density functional theory (DFT.) calculations. In this work, MD simulations of the CdZnTe clusters are performed by means of LAMMPS by using bond order potential (BOP). MD simulations are carried out at different temperatures to study the segregation phenomena of Cd, Zn and Te atoms, and deviation of clusters and heat capacity. After that,...
