Abstract

This paper presents the first optical and spectroscopic characterization of zirconium based fluoride planar waveguides ZE (ZrF₄-ErF₃) and ZLE (ZrF₄-LaF₃-ErF₃) that have been fabricated by Physical Vapor Deposition (PVD) in dual evaporation configuration [1]. Transparent thin films have been obtained by adjusting vaporization temperature, composition of the ZrF₄-based glass and the LaF₃-ErF₃ batch. In order to improve resistance to moisture, a low refractive index (~1.32) KAlF₄ cladding has also been deposited. Infrared spectrum of the waveguides has confirmed the protecting role of the cladding layer for the active layer regarding hydrolysis. Luminescence measurements on waveguide samples have shown promising properties compared with the bulk samples, indicating that this system may be suitable for ceramization like in bulk configuration [2-3].
