Optical Micro- and Nanofiber Pulling Rig
摘要:
我们回顾了使用氢/氧火焰刷技术制备绝热光学微米和纳米纤维的方法。火焰沿着光纤扫描,光纤同时被两个平移台拉伸。锥形光纤制造是可重复的,并产生具有指数或线性分布的高度绝热的锥形。详细介绍了火焰刷钻机的设置和使用的各种参数。从文献中获得的信息进行了汇编,并进一步的细节,有必要有一个功能的牵引钻机包括在内。这应该使读者能够制造各种锥形轮廓,同时实现基模传播的~ 99%的绝热透射。利用该装置,获得了光波导中高阶模的透射率在85-95%之间的结果。
英文摘要:
We review the method of producing adiabatic optical micro- and nanofibers using a hydrogen/oxygen flame brushing technique. The flame is scanned along the fiber, which is being simultaneously stretched by two translation stages. The tapered fiber fabrication is reproducible and yields highly adiabatic tapers with either exponential or linear profiles. Details regarding the setup of the flame brushing rig and the various parameters used are presented. Information available from the literature is compiled and further details that are necessary to have a functioning pulling rig are included. This should enable the reader to fabricate various taper profiles, while achieving adiabatic transmission of ~ 99% for fundamental mode propagation. Using this rig, transmissions ranging from 85-95% for higher order modes in an optical nanofiber have been obtained.
