A new basic structure of a dispersive-compensation filter, called a chirped-cavity dispersion-compensator (CCDC) filter, was designed to offer the advantages of small ripples in both reflectance and group-delay dispersion (GDD). This filter provides a high dispersion compensation, like the Gires-Tournois interferometer (GTI) filter, and a wide working bandwidth, like the chirped mirror (CM). The structure of the CCDC is a cavity-type Fabry-Perot filter with a spacer layer (2 mH or 2 mL) and a chirped high reflector. The CCDC filter can provide a negative GDD of -50 fs2 over a bandwidth of 56 THz with half the optical thickness of the CM or the GTI.
一种名为啁啾腔色散补偿器（CCDC）滤波器的新型色散补偿滤波器基本结构被设计出来，以兼具反射率和群延迟色散（GDD）方面纹波小的优点。该滤波器像吉雷斯 - 图诺干涉仪（GTI）滤波器一样提供高色散补偿，又像啁啾镜（CM）一样具有宽工作带宽。CCDC的结构是一种带有间隔层（2 mH或2 mL）和啁啾高反射镜的腔型法布里 - 珀罗滤波器。CCDC滤波器能在56 THz带宽内提供 -50 fs² 的负GDD，且光学厚度仅为CM或GTI的一半。
