for erbium ion in light-emitting layer with light activated process and other chemical reaction, it is necessary to anneal the devise with high temperature in fabrication process.
为了让发光层内铒离子具有光活化及其他的化学反应的发生,在制程中热退火是必须的。
we demonstrate a multi-wavelength erbium-doped fiber laser (edfl) using erbium gain and four-wave mixing (fwm) effect in a piece of erbium-doped fiber (edf) with high erbium ion concentration.
