Group Delay Dispersion – What it is and why care about it?

WebMathematically GDD it is the rate of change of the Group Delay with respect to angular frequency, and thus GDD has units of time squared. Usually it is expressed in units of femtoseconds (fs) squared. Many system optics, like microscope objectives, contribute positive GDD and necessarily cause pulse chirping. WebThe GDD of bulk optics can be accurately calculated using the Sellmeier equations, but calculating the GDD of coated optics can be tricky. Figure 1 shows a perfectly …
