The centrosymmetric nature of silica fibre precludes the realisation of second-order
nonlinear processes in optical fibre systems. Recently, the integration of 2D materials with …

Presented here is a review of recent progress in the nascent field of glass-clad
semiconductor core optical fibers. Such fibers, generally focused to-date on silicon and …

Thermal poling of glasses induces structural and compositional modification and breaks
central symmetry of these initially isotropic media. In spite of numerous experimental data …

It is generally well known that not only the sodium itself, but also the non‐bridging oxygen
(NBO) sites associated with sodium ions are largely responsible for the surface reactivity of …

The generation of 236 mW of second-harmonic power in a 32-cm-long periodically poled
silica fiber, corresponding to an average conversion efficiency of 15.2±0.5%, is reported …

1.1 Overview Silica glass is technologically very important, especially in
telecommunications, because of its excellent properties such as strength and the ability to …

The mechanical and mechanochemical properties of soda lime silica (SLS) glass surfaces
can vary with the sodium ion (Na+) concentration in the subsurface region. Changes in …

Quantum sources that provide broadband biphotons entangled in both polarization and time-
energy degrees of freedom are a rich quantum resource that finds many applications in …

A step-index tellurite optical fiber with loss∼ 0.02 dB/m at∼ 1545 nm was fabricated based
on TeO_2− Bi_2O_3− ZnO− Na_2O glass. With a nanosecond laser operated at∼ 1545 …

All-fiber functional devices are superior to conventional optical crystals for next-generation
integrated optics owing to their natural compatibility with optical fiber systems. Nonlinear …
