摘　　要：本文首次提出利用同一透射光栅的两次衍射进行色散补偿，其补偿量线性可调．通过理论分析得到其补偿能力与光栅常数、衍射级以及装置尺寸ｂ有关．提出增大补偿能力和简化装置的方案．A device which performs the function of tunable dispersion compensation linearly based on a transmission grating with two times diffraction on the opposite direction is introduced in this paper at first time to our knowledge.The ability of its compensation is observed to be related to the grating constant,the order of the diffraction and the size of this device by analyzing theoretically.In order to increase the compensation capability and simplify this device,different means are presented.

关 键 词：色散补偿 透射光栅 衍射级 光栅常数
