Homogeneity Characterization of Photonic Crystal Fiber
Abstract
We demonstrate the use of spontaneous four- wave mixing (FWM) as a method to determine the homogeneity of photonic crystal fibers. Two fibers are drawn under different conditions and characterized optically. The optical cross sections of the fibers are modeled in a full vectorial finite element analysis software to determine the effective propagations constants. The modeled propagation constants can be used to calculate the four- wave mixing wavelength peak and compared to the measured value. Given the resolution of the features inside photonic crystal fibers, measuring the four- wave mixing peak wavelength serves as a direct measure on the homogeneity of the fiber, in particular the key metric used was the spatial variation of the four-wave mixing wavelength along the length of the fiber. This report presents research conducted by Optical Sciences code 5600 for the development of high power fiber laser sources based on four-wave mixing.
