THEORETICAL STUDY OF DISPERSION COMPENSATION WITH TRANSMISSION GRATING
利用透射光栅的衍射进行色散补偿的理论研究

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.
