| contents | We discover three novel classes of pulse-train waveforms in an optical Kerr nonlinear medium
possessing all orders of dispersion up to the fourth order. We show that both single- and double humped pulse-trains can be formed in the nonlinear medium. A distinguishing property is that these
structures have different amplitudes, widths and wavenumbers but equal velocity which depends on
the three dispersion parameters. More importantly, we find that the relation between the amplitude
and duration of all the newly obtained pulse-trains is determined by the sign of a joint parameter
solely. The results show that those optical waves are general, in the sense that no specified conditions
on the material parameters are assumed. Considering the long-wave limit, the derived pulse-trains
degenerate to soliton pulses of the quartic and dipole kinds. |
