An Efficient Method of Monitoring PCF Properties during the Fabrication Process

摘要

It is very important for the photonic crystal fiber character to monitor its properties synchronously during the fabrication process so that a series of draw parameters can be efficiently optimized as PCF used to be produced. In this paper, we reported an efficient method to monitor PCF properties with the cross-section of the photonic crystal fiber collected by microscope and CCD. The structure parameters of the cross-section of PCF are fast picked up by digital process technology and the properties of the PCF produced are efficiently analyzed by a finite element method. The method is very helpful in optimizing the draw parameters and improving the properties of PCF.
