Effect of WO3 on the spectroscopic properties of Er3+-doped telluride glass
摘要
为了满足光通信技术发展对光放大器材料的带宽要求,采用固相法制备了掺铒碲钨酸盐玻璃,研究了其光谱性质和热稳定性。用Judd-Ofelt理论计算了光谱的强度参量,根据McCumber理论计算了受激发射截面,其最大受激发射截面为1.85×10-20cm2,荧光半峰全宽最大值为104nm;用差热法分析了玻璃的热稳定性,析晶温度和转变温度之差最大值为131℃。结果表明,掺铒碲钨酸盐玻璃是一种良好的宽带放大器材料。
Abstract
Because of the need for broad bandwidth of optical material in optical communication, tungsten-tellurite glass was prepared by means of solid-phase. Its optical properties and thermal stability were studied. Spectral intensity parameters were calculated based on Judd-Oflet theory. According to the McCumber theory, its emission cross section was simulated with a maximum value of 1.85 × 10-20cm2 and a maximum full width half maximum of 104nm. The thermal stability of glass was analyzed with a maximum differential thermal temperature ΔT of 131℃(difference between glass transition temperature Tg and crystallization temperature Tx ). The results show that the erbium-doped tungsten-tellurite glass is a good material for broad bandwidth amplifiers.
