零模间色散三芯光子晶体光纤
Three-core photonic crystal fiber with zero intermodal dispersion
摘要
Abstract
In order to analyze the intermodal dispersion ( IMD ) between two random supermodes in a three-core photonic crystal fiber ( PCF) with low refractive index material doping into the core , the intermodal dispersion coefficient and zero IMD wavelength as the function of core index and design parameters were investigated by using full -vector finite element method.The results show that zero intermodal dispersion can be achieved at two common wavelengths of 1.31μm and 1.55μm by adjusting the structure parameters , i.e., core index, core diameter, air hole diameter and the pitch of air holes.The result is helpful to eliminate the pulse distortion due to intermodal dispersion between different modes in PCFs based on mode division multiplexing and realize the zero IMD mode division multiplexing technology .关键词
