A.S.E. Source at 1550nm for IFOG Applications

Abstract

We performed annealing studies for the Al2O3 guides, and we have identified the best annealing temperatures in terms of lifetimes and luminescence. For example a 0.1% Er doped film is best annealed at 500 C for a period of 1 hour in an oxygen ambient atmosphere. The lifetimes measured with 0.1% Er is around 4 ms, which is a factor of two less than as seen in fiber for a tenth of that doping level but our previous measurements indicate increased gain. Measurements on the Al2O3 guides showed 20% improvement of lifetime achieved by annealing. Erbium and Ytterbium codoped films had one half the lifetimes of those doped with Erbium alone.
