Polarization conversion in a silica microsphere.
We experimentally demonstrate controlled polarization-selective phenomena in a whispering gallery mode resonator. We observed efficient ( approximately 75%) polarization conversion of light in a silica microsphere coupled to a tapered optical fiber with proper optimization of the polarization of the propagating light. A simple model treating the microsphere as a ring resonator provides a good f...
متن کاملErbium-implanted silica microsphere laser
Spherical silica optical microresonators were doped with erbium ions by ion implantation at energies of 925 keV and 2.05 MeV using a rotating stage. After thermal annealing at 800 C, light was coupled into the microsphere using a tapered optical fiber. An optical quality factor as high as 1.9 · 10 was observed at k = 1450 nm, corresponding to a modal loss of only 0.01 dB/cm. When pumped at 1450...
متن کاملHypervelocity impact of a steel microsphere on fused silica sheets
We use the commercial finite element software Abaqus to study three-dimensional deformations of glass panels impacted at normal incidence by a 0.5 mm diameter steel sphere moving at about 3 km/s and having kinetic energy of approximately 2.3 J. We quantify effects of the critical erosion strain and the impact speed upon the conchoidal fracture diameters developed on the frontand the backsurface...
متن کاملElectrostatically tuned interactions in silica microsphere-polystyrene nanoparticle mixtures.
We explore the generality of nanoparticle haloing as a novel colloidal stabilization mechanism in binary mixtures of silica microspheres and polystyrene nanoparticles. By selectively tuning their electrostatic interactions, both the initial microsphere stability and the role of nanoparticle additions are varied. Adsorption isotherm and zeta potential measurements indicate that highly charged na...
متن کاملSynthesis of Mesoporous Silica Microsphere from Dual Surfactant
A new procedure is reported to synthesis mesoporous silica micro sphere for the first time. In these method two surfactants namely Span 80 and Tween 80 were used. Small angle X ray diffraction and N2 adsorption analysis shows the synthesized material has mesoporous property. The material has spherical morphology with 1-10 μm particle size. Beside the material found to have microcapsule property...
