We present simulation results for supercontinuum generation using As2S3 chalcogenide photonic crystal fibers. We found that more than 25% of input power can be shifted into the region between 3 μm and 5 μm using a pump wavelength of 2 μm with a peak power of 1 kW and an FWHM of 500 fs. The broad dispersion profile and high nonlinearity in As2S3 chalcogenide glass are essential for this applicat...

We demonstrate how the radiat performance of Ag-chalcogenide glass r fabricated on a flexible substrate can b modifications of spacing between electrodes.

PURPOSE This study was conducted to evaluate the effects of full-coverage all-ceramic zirconia, lithium disilicate glass-ceramic, leucite glass-ceramic, or stainless steel crowns on antagonistic primary tooth wear. MATERIALS AND METHODS There were four study groups: the stainless steel (Steel) group, the leucite glass-ceramic (Leucite) group, the lithium disilicate glass-ceramic (Lithium) gro...

The main properties (mechanical, thermal and chemical) and clinical application for dental restoration are demonstrated for three types of glass-ceramics and sintered polycrystalline ceramic produced by Ivoclar Vivadent AG. Two types of glass-ceramics are derived from the leucite-type and the lithium disilicate-type. The third type of dental materials represents a ZrO2 ceramic. CAD/CAM technolo...

IR-transparent chalcogenide glass-ceramics were fabricated through a careful ceramization process of the as-prepared 65GeS2 25Ga2S3 10LiI glasses at a temperature of 403 1C for various durations. Owing to the precipitation of LixGaySz crystals with a Ga2S3-like structure, clear second-harmonic generation was observed in the sample crystallized at 403 1C for 60 h, which has a greatly improved re...

We demonstrate the excitation of guided modes in thin layers of strongly absorbing chalcogenide glasses. These modes are similar to surface plasmon polaritons in terms of resonance width and shift with changes in the permittivity of the surrounding medium. We exploit these characteristics to demonstrate a high sensitivity chalcogenide glass refractive index sensor that outperforms gold surface ...

In the proposed paper, we report chalcogenide As2Se3 glass Photonic Crystal Fiber (PCF) for dispersion compensating application and also demonstrate other dispersion properties (negative and zero dispersion) of As2Se3 glass PCF in different wavelength windows with hexagonal arrangement of air holes in the cladding using Improved Fully Vectorial Effective Index Method (IFVEIM).

This study was performed to evaluate the effect of a lithium-disilicate spray-liner application on both the bond strength between zirconia cores and heat-pressed lithium-disilicate glass-ceramic veneers, and the fracture strength of all-ceramic zirconia crowns. A lithium-disilicate reinforced liner was applied on the surface of a zirconia core and lithium-disilicate glass-ceramic was veneered o...

Second-order optical properties of thermally poled arsenicgermanium sulfide glasses have been investigated. Parallel studies of glass structure changes upon poling and/or visible cw-laser irradiation and complete SHG quantitative analysis have been performed. Key parameters and poling mechanisms influencing largely SHG stability and efficiency have been pointed out. ©2013 Optical Society of Ame...
