Broadband supercontinuum (SC) generation requires host material attributes defined by
both optical and physical properties and the material's manufacturability. We review and …

Infrared gradient refractive index (GRIN) material lenses have attracted much attention due
to their continuously varying refractive index as a function of spatial coordinates in the …

While widely used in the visible, radial gradient refractive index (GRIN) lenses are still
elusive in the IR waveband. In this paper we introduce a new method based on spatially …

Femtosecond laser induced changes and writing in optical materials have proven to be an
excellent route to the production of high‐quality micro‐and nanofabrication of functional …

Abstract Infrared (IR) glass–ceramics (GCs) hold the potential to dramatically expand the
range of optical material solutions available for use in bulk and planar optical systems in the …

The size and weight of conventional imaging systems is defined by costly non‐planar lenses
and the complex lens assemblies required to minimize optical aberrations. The ability to …

Chalcogenide glasses show a unique potential for creating gradient refractive index (GRIN)
lenses, which would reduce the size and weight of infrared thermal imaging system and …

A series of ten Ge x Ga y Se 1-xy glasses within the topological constraint regime of< r>= 2.3
to 2.8 were processed for physical property testing to compare measured to calculated …

The manufacturing of low loss chalcogenide glasses (ChGs) for optoelectronic applications
is ultimately defined by the concentration of impurities present in starting materials or …

The development of gradient index free-form micro-optic components dedicated to the mid-
infrared range is challenging due to the lack of appropriate technology. We propose a …
