Femtosecond Laser Fabrication of Gradient Refractive Index Micro-Lenses in Chalcogenide Glass for Applications in Visible and Infrared Region

Résumé

Gradient refractive index (GRIN) lenses are optical components having spatial variations of in the material [1]. GRIN have been widely used for several applications such as correction aberrations [2], fiber coupling [3], imaging systems [4]. Many techniques developed fabrication lenses: chemical vapor deposition, ion exchange or neutron irradiation [5]. However, these cannot be applied all materials because their use depends composition [6]. In addition, femtosecond laser direct writing (FLDW) method is a very flexible technique to modify materials. This powerful allows controlling inscribed shape [6], especially scale <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mu \mathrm{m}$</tex> . this work, we focus on micro-lenses chalcogenide glasses (ChG) using FLDW method.
