不同形状介质腔与塑料光纤双锥的活动耦合特性

Adjustable coupling performance of plastic fiber dual-taper and different shape medium cavity

研究了利用球形体、圆柱体、长方体 (统称介质腔 )实现光能在两根塑料光纤双锥之间的耦合。测量了光纤双锥的发射效率和介质腔耦合效率与其接收表面积、锥腔间距之间的关系。该器件能进一步发展为一种新型的光分插复用器。

Light energy transfering between two plastic fiber dual-taper by using sphere,cylinder and rectangle cavity (all called medium cavity) is reported. The emitting efficiency of fiber dual-taper is measured. The coupling efficiency of medium cavity relative to its receiving surface area and distance between taper and cavity are also measured. This devices can be used to develop a new type optical add-drop multiplexer.
