摘要：
We report experimental results from an erbium-doped gallium phosphide microdisk resonator pumped by a Ti-sapphire laser at 980 nm. Fabrication and characterization of the microdisk resonator are discussed. Enhanced Er+3 intra-4f-shell photoluminescence was observed in the microdisk resonator due to microcavity effect and compared to a thin film sample. At low pumping power intensity, the photoluminescence from erbium-doped gallium phosphide microdisks is an order stronger than that from a thin film sample.© 1995 American Institute of Physics.
