Abstract

In this paper, we report on fabrication process of ordinary and rare-earth-doped aluminum phosphate sol-gel films and their physical and optical properties. The gel films are transparent, hard and of good optical quality as glass. High doping of rare-earths (Nd³⁺, Er³⁺ and Yb³⁺) are realized in films with this technique. This type of doped films offer potential benefits for applications in the field of active integrated optics devices for optical telecommunication systems.
