Low-loss optical communication dispersion compensator and dispersion compensation method thereof

The invention provides a low-loss optical communication dispersion compensator and a dispersion compensation method thereof. The low-loss optical communication dispersion compensator comprises a chirped grating fiber core, a positive electrostriction layer, a negative electrostriction layer, a positive electrode layer, a negative electrode layer and an electric tuning element. The low-loss dispersion compensation scheme is realized; the tunable effect of a dispersion compensation range is realized on the basis of the electrodeformation effect of an electrodeformation organic material; and thelow-loss optical communication dispersion compensator has the advantages of being wide in applicable dynamic range, high in tuning speed, high in tuning precision, good in robustness and simple in structure. 本申请提供种低损耗光通信色散补偿器及其色散补偿方法，包括啁啾光栅纤芯、正向电致伸缩层、负向电致伸缩层、正向电极层、负向电极层以及电调谐单元。本申请实现了低损耗的色散补偿方案，且基于电致形变有机材料的电致形变效应，实现色散补偿范围的可调谐，具有适用动态范围宽、调谐速度快、调谐精度高且鲁棒性好、结构简单的优点。
