Observation Of Resonance Modes In Inas/ingaasp/inp Quantum Dot Microdisk Resonators

We present the development of quantum dot microdisk resonators grown by Chemical Beam Epitaxy (CBE). Two stacked layers of InAs Quantum Dots (QDs) embedded in a lattice-matched InGaAsP (λ g=1.4 μm) are grown on (100) InP substrate. Evidence of the presence of resonant modes are observed both by eletroluminescense and absorption spectra at room temperature. © The Electrochemical Society.141505509McCall, S.L., Levi, A.F.J., Slusher, R.E., Pearton, S.J., Logan, R.A., (1992) Appl.

Stadium Cavity Optical Resonator Fabricated By Focused Ion Beam

We have fabricated micro-disk and micro-stadium optical resonators based on conventional InGaAsP/InP multi-quantum well laser epitaxial structures, using a hybrid process by Focused Ion Beam milling and selective wet chemical etching. Resonators with very smooth walls were obtained allowing the observation of optical modes of the stadia with a 15 nm separation. This modal separation is an evidence of the beating between stadium scar modes. © The Electrochemical Society.231455460Del'Haye, P., Schliesser, A., Arcizet, O., (2007) Nature, 450 (7173), p. 1214Heller, (1984) PRL, 53, p. 1515Bogomolny, (1988) PhysicaD, 31, p. 169Gmachl, C., (1998) Science, 280, p. 1556Munoz, S.N., VonZuben, A.A.G., Frateschi", N.C., (2009) JAP, 105, p.

Induced Optical Losses In Optoelectronic Devices Due Focused Ion Beam Damages

A study of damages caused by gallium focused ion beam (FIB) into III-V compounds is presented. Potential damages caused by local heating, ion implantation, and selective sputtering are presented. Preliminary analyzes shows that local heating is negligible. Gallium implantation is shown to occur over areas tens of nanometers thick. Gallium accumulation as well as selective sputtering during III-V compounds milling is expected. Particularly, for GaAs, this effect leads to gallium segregation and formation of metallic clusters. Microdisks resonators are fabricated using FIB milling with different emission currents to analyze these effects on a device. It is shown that for higher emission current, thus higher implantation doses, the cavity quality factor rapidly decreases due optical scattering losses induced by implanted gallium atoms.728791Vallini, F., Figueira, D.S.L., Jarschel, P.F., Barea, L.A.M., von Zuben, A.A.G., Filho, A.S., Frateschi, N.C., Effects of Ga + milling on InGaAsP quantum well laser with mirrors milled by focused ion beam (2009) J.

A-siox<er> Active Photonic Crystal Resonator Membrane Fabricated By Focused Ga+ Ion Beam

We have fabricated thin erbium-doped amorphous silicon suboxide (a-SiOx) photonic crystal membrane using focused gallium ion beam (FIB). The photonic crystal is composed of a hexagonal lattice with a H1 defect supporting two quasi-doubly degenerate second order dipole states. 2-D simulation was used for the design of the structure and full 3-D FDTD (Finite-Difference Time-Domain) numerical simulations were performed for a complete analysis of the structure. The simulation predicted a quality factor for the structure of Q = 350 with a spontaneous emission enhancement of 7. Micro photoluminescence measurements showed an integrated emission intensity enhancement of ∼2 times with a Q = 130. We show that the discrepancy between simulation and measurement is due to the conical shape of the photonic crystal holes and the optical losses induced by FIB milling. © 2012 Optical Society of America.20171877218783Pavesi, L., Lockwood, D.J., Silicon photonics (2004) Topics in Applied Physics, , SpringerEnnen, H., Scheneider, J., Pomrenke, G., Axmann, A., 1.54m luminescence of erbium?implanted III?V semiconductors and silicon (1983) Appl.
