Single-phase, polycrystalline ErxY2-xSiO5 thin films were deposited by reactive ion-beam sputter deposition and rapid thermal annealing. Due to the crystalline nature, the silicate thin films provide peak Er3+ emission cross-section of 0.9 ± 0.02 × 10−20 cm2 that is higher than that in silica. Optical gain, with near 60% inversion, is achieved via optical pumping of a single-mode, ridge-type waveguide with the silicate core with an Er concentration of 1.7 × 1020 cm−3. Analysis of pump-power dependence of the optical gain and spontaneous emission intensity of Er3+ indicate that the gain is limited by cooperative upconversion process, whose coefficient is determined to be (8 ± 3) × 10−17 cm3/sec.
