Abstract
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 ( or ) and a chirped high reflector. The CCDC filter can provide a negative GDD of over a bandwidth of with half the optical thickness of the CM or the GTI.
