Three-Dimensional Mid-Infrared Photonics: Recent Progress in Ultrafast Laser Writing of Waveguides

Abstract

We present here our recent progress in the three-dimensional (3D) direct laser writing (DLW) of step-index core waveguides inside diverse technologically relevant dielectric substrates, with specific emphasis on the demonstration of DLW mid-infrared waveguiding in the whole transparency range of these materials.
