我们报告了飞秒激光微加工的有源波导在一个新的掺铒磷碲酸盐玻璃通过一个紧凑的腔倾倒Yb基写入系统。研究了玻璃的光谱特性，并对飞秒激光写入光波导的有源和无源性能进行了表征。特别地，在光通信的整个C+L波段（1530- 1610 nm）中证明了内部增益。
We report on fs-laser micromachining of active waveguides in a new erbium-doped phospho-tellurite glass by means of a compact cavity-dumped Yb-based writing system. The spectroscopic properties of the glass were investigated, and the fs-laser written waveguides were characterized in terms of passive as well as active performance. In particular, internal gain was demonstrated in the whole C+L band of optical communications (1530- 1610 nm).
