An analysis is given for the temporal compression of linearly chirped pulses propagating in strongly dispersive media. The wave vector k(ω) of the dispersive medium is expanded in a Taylor series through terms cubic in frequency. Analytic expressions are developed for the shape of the compressed pulse, and numerical examples given to illustrate the influence of the cubic term in k(ω). This term is shown to give asymmetric broadening of the compressed pulse envelope, even when it is very small in magnitude compared to the lower-order terms in the Taylor series.
