摘要
为了满足光通信中对光纤端面镀多层膜的特殊需求, 分析了光纤端面镀制截止滤光膜所存在的难点问题, 利用TFCalc薄膜设计软件, 采用解析法设计了一个初始膜系, 再结合梯度优化法对初始膜系进行优化处理, 成功设计出具有较好光谱性能的光纤端面截止滤光膜的膜系, 并对德国莱宝APS1104型镀膜机进行了内部结构和镀制工艺的改进, 最终采用离子源辅助沉积进行低温镀制, 获得了性能优良的光纤端面截止滤光膜。结果表明, 在光纤端面镀制多层的截止滤光膜, 虽然存在很多困难, 但选择合适的膜系和镀制工艺, 依然能获得符合实际要求的滤光膜。
Abstract
In order to satisfy the especial requirement of depositing multi-layer coating on the end of fiber, the difficulties in the coating deposition on the end of fiber was analyzed. Firstly, an initial formula was designed by means of resolution method. Then it was optimized with gradient optimization method by using TFCalc formula design software. Finally, the formula of interference edge filter film on the end of fiber was obtained with good spectral properties. The internal structure and deposition technology of LEYBOLD APS1104 deposition machine made in Germany was improved to deposit the designed formula by using ion assistant deposition at low temperature, coating with good performance was acquired. The results show that it is difficult to deposit interference edge filter film on the fiber end, however, the requirements of the interference edge filter film can be met if choosing suitable formula and deposition technology.
