色散补偿光子晶体光纤结构参数对其色散的影响
Effects of structure parameters on the dispersion properties of dispersion compensation photonic crystal fiber∗
摘要
Abstract
Photonic crystal fiber has great potential applications such as dispersion compensation due to its adjustable and flexible dispersion characteristics. In this paper, we design a dispersion compensation photonic crystal fiber, simulate the dispersion characteristics by the finite-difference frequency-domain method, and analyse the effects of the structure parameters air hole spacingΛ and air-filling fraction d/Λ on the dispersion of photonic crystal fiber theoretically. And we also fabricate three photonic crystal fibers with different structural parameters. Through the comparison and analysis of their dispersion curves, we have the following conclusions:the dispersion coefficient increases with air hole spacingΛ and air-filling fraction d/Λ increasing when the air hole spacing of photonic crystal fiber is about 1 µm, but the dispersion is more sensitive to the change of air hole spacingΛ than to air-filling fraction d/Λ, and the effect of air hole spacing on the dispersion coefficient decreases with the increase of air hole spacing. One of the photonic crystal fibers realizes the designed structure:its dispersion coefficient is 241.5 ps·nm−1·km−1, relative dispersion slope is 0.0018 at 1550 nm, it has good ability in dispersion compensation.关键词
