The successful migration from electronic to photonic devices relies on the fabrication and integration of multiple optical components, including active devices such as lasers or amplifiers, on a common planar substrate to reduce their size, cost and power consumption, while maintaining their compatibility with the current fiber technology. Doped glasses are among the most promising materials for the development of active integrated devices due to their excellent optical properties and ease of preparation at a reasonable cost. Yet, their application requires first the fabrication of high quality thin films a few microns thick with good photoluminescence performance.
In this contribution we will show that pulsed laser deposition (PLD) is very attractive for this purpose, since it allows the synthesis of metastable phases of complex oxides in thin film configuration as well as their nanostructuration through the incorporation of rare earth (RE) ions as functionalizing elements. Thus, opening a realm of material function and design possibilities. We will review how alternate PLD allows the synthesis of nanostructured film glasses with a controlled RE concentration and an in-depth distribution that can be predesigned at the nanometer scale. This approach will be illustrated in the case of germanate and tellurite film glasses doped and co-doped with different RE ions. We will focus on the experimental parameters that have a direct impact on the concentration and distribution of RE ions and their effect on the photoluminescent properties and, finally, their potential in light amplification applications will be discussed.
