摘要

介绍了用PVD技术在ZBLAN或CaF2衬底上制备稀土掺杂氟化物波导的激光光谱。在沉积前，通过光刻工艺在衬底上获得了PZG成分的通道波导。报道了1.5 μm的Nd3+荧光和1.55 μm的铒荧光，包括衰减时间与R.E.浓度的关系。最后，我们在掺1 at% nd的PZG波导中测量了1.05 μm处3.8 dB/ cm的信号放大。

Rare earth doped PZG fluoride glass channel waveguides: spectroscopy and signal amplification

Laser spectroscopy of R.E. doped fluoride waveguides elaborated by PVD technique on ZBLAN or CaF2 substrate is presented. Channel waveguides of the PZG composition were obtained photolithography process on the substrate before deposition. Nd3+ fluorescence at 1.5 μm as well as erbium fluorescence at 1.55 μm are reported including decay time dependence with R.E. concentration. Finally, we have measured a signal amplification of 3.8 dB/ cm at 1.05 μm in a 1 at% Nd-doped PZG waveguide.
