二氧化硅基Optical Fibers中的发光离子

Luminescent Ions in Silica-Based Optical Fibers

Bernard Dussardier, Wilfried Blanc, Gérard Monnom

摘要:

我们提出了一些我们的研究活动,致力于掺杂硅基光纤,旨在了解发光离子,如稀土和过渡金属元素的光谱特性。研究了局域环境对掺杂的影响:稀土离子间的能量转移机制、铬离子价态的控制、局域声子能量对铥离子发射效率的影响以及氧化物纳米颗粒诱导铒离子发射的展宽。了解这些效应对于光子学的应用是必不可少的。

英文摘要:

We present some of our research activities dedicated to doped silica-based optical fibers, aiming at understanding the spectral properties of luminescent ions, such as rare-earth and transition metal elements. The influence of the local environment on dopants is extensively studied: energy transfer mechanisms between rare-earth ions, control of the valence state of chromium ions, effect of the local phonon energy on thulium ions emission efficiency, and broadening of erbium ions emission induced by oxide nanoparticles. Knowledge of these effects is essential for photonics applications.
