This paper describes a novel fiber designed to produce uniform illumination in angular space along its length. The mechanism of light extraction from the silica glass guiding region is due to nano-sized gas filled voids formed during fiber preform co

In this work, we study the thermal conductivity of densified soda lime borosilicate glasses with varying B2O3/SiO2 ratio. Densification is induced by hot compression up to 2 GPa at the glass transition temperature. We find that the structural and mec

Despite their transformative role in our society, oxide glasses remain brittle. Although extrinsic postprocessing techniques can partially mitigate this drawback, they come with undesirable side effects. Alternatively, topological engineering offers

Laser-Induced Swelling of Borosilicate Glasses-An Analysis of Associated Microstructural Development

International Journal of Applied Glass Science. 5:267-275
Borosilicate glass swelling by laser irradiation is an unusual phenomenon. The height of raised hemisphere on the swelled glass surface can be approximately 10–15% of the 1–3 mm glass thickness. To understand the mechanism of glass swelling, the

Fiber-based cylindrical light diffusers are often used in photo dynamic therapy to illuminate a luminal organ, such as the esophagus. The diffusers are often made of plastic and suffer from short diffusion lengths and low transmission efficiencies ov

As optical fiber penetrates further into the communications infrastructure and comes closer to the home or business, higher optical power levels are expected. Several studies have shown that sharply bent optical fiber will fail prematurely when expos
