Yb-Bi codoped magnesium germanate glasses were prepared. Their optical properties were investigated by absorption, luminescence spectra and luminescence decay lifetime and compared with single Bi-doped glass. The emission intensity of Yb-Bi codoped glass (MGBY) is ~10 times larger than that of single Bi-doped sample (MGB). The single-pass optical amplification was measured on a traditional two-...

Future generation optical networks are expected to provide ultra broadband optical communication to continuously growing fiber transmission requirements. In this context, Bismuth and Erbium (Bi/Er) codoped glass fibers symbolize an important aspect as it has offered a promising active laser medium for ultra-bandwidth communication. Many studies have been demonstrated that Bi/Er codoped glass op...

Microbubble whispering gallery resonators have the potential to become key components in a variety of active and passive photonic circuit devices by offering a range of significant functionalities.

Evanescent field coupling to the microbubbles was achiev...

We present a fully functional material extrusion printer for optically transparent glass. The printer is comprised of scalable modular elements, able to operate at the high temperatures required to process glass from a molten state to an annealed product. We demonstrate a process enabling the construction of 3D parts as described by Computer Aided Design (CAD) models. Processing parameters such...

in this study, silver nanoparticles were synthesized by chemical reduction method at different concentrations of ag colloid in the range of 500-16000 ppm. nanoparticles were deposited by spin coating method on pre-etched glass and si substrates. structural, optical and electrical properties of the samples were studied using scanning electron microscopy equipped with edax, uv-vis spectrophotomet...

Surface roughness is a significant parameter which determines the efficiency of optical components. Surface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. It is meaningful to rapid evaluate the surface roughness through the measurement of different grinding parameters. In this study, a cup diamond wheel (D64) is used in grinding pr...

The effect of polymeric coatings on the static fatigue of double-coated optical fibers is investigated. A closed form solution of the tensile stress in the glass fiber under the action of a constant tensile force in the fiber’s axial direction is obtained using viscoelastic theory. The tensile force is applied to the glass fiber and polymeric coatings. The applied tensile fore is gradually tran...

Bi2O3-based glasses are very attractive from the viewpoints of low-melting, high refractive index, and crystallization, and the research on their glasses and glass-ceramics is at the frontiers of glass science and technology. Non-linear optical Bi2ZnB2O7 crystal lines with a high orientation were patterned in 3Sm2O3-30.3Bi2O3-33.3ZnO-33.3B2O3 glass by using a laser-induced crystallization techn...
