WebGroup-delay dispersion. A closely related yet independent quantity is the group-delay dispersion (GDD), defined such that group-velocity dispersion is the group-delay dispersion per unit length. GDD is commonly used as a parameter in characterizing layered mirrors, where the group-velocity dispersion is not particularly well-defined, yet the ... WebThe group delay has the units of a time (e.g. picoseconds) and generally (in dispersive media) depends on the optical frequency (→ group delay dispersion, chromatic dispersion) and possibly on the polarization state (→ polarization mode dispersion) and the optical mode (→ intermodal dispersion) in the case of a waveguide.. As a simple example, for …

WebThe group delay results for the three S-parameter element circuits are plotted in Figure 5.
