摘要：

We present our investigations into the fabrication of three-dimensional microoptical elements by the direct femtosecond laser writing of a germanium-silicon photosensitive hybrid material. Germanium glass composites are very interesting for optical applications as they are photosensitive, and maintain high optical transparency in the visible and near-infrared bands of the spectrum. Here, we have used a germanium containing hybrid material to make nanophotonic structures and microoptical elements such as photonic crystal templates, prisms and spatial polarization plates, both on flat surfaces and fiber tips. Our results show that this germanium silicate composite is an excellent material for microoptics fabrication. (C) 2012 Elsevier Ltd. All rights reserved.
