Fabrication and characterization of sol‐gel planar waveguides doped with rare‐earth ions

Silica‐titania sol‐gel planar waveguides were deposited on silica glass disks by spin coating. Fluorescence lifetimes as high as 375 μs were measured in neodymium‐doped sol‐gel planar waveguides and 1.78 ms for an erbium‐doped film. Quenching was found to occur for the former at concentrations above 1 at. % of neodymium.
