摘要：

Microstructure resonators have attracted considerable attention because of their versatility for signal processing applications. We use our Er3+ doped telluride glass to fabricate Er3+ glass microsphere. The excitation of whispering-gallery modes is realized by coupling from an angle-polished single-mode optical fiber tip to an optical microsphere cavity. In the experimental setup, one fiber was used as an input coupler and the other fiber was used as an output coupler. 975nm fiber pigtailed laser diode was used to side pump the microspheres. Very nice whispering-gallery modes (WGM's) near 1.5mum were observed successfully. Signal enhancement was observed in this Er3+ doped telluride glass microsphere with a radius around 50mum. The best enhancement of this Er3+ doped telluride glass microsphere reaches 12dB.
