The dynamic characteristics of an InGaAs/InP lattice-matched V-groove quantum wire laser are theoretically considered. The differential gain of the laser is derived from the k-p theory, taking into account nonparabolicity of both bands, the conduction and the valence band. We investigate the bandwidth of the laser versus its optical confinement, driving current and roll-off time, including nonlinear gain suppression. In spite of solid differential gain and the D-factor comparable with the best-performance QW laser, the maximum bandwidth of the laser is limited to about 20GHz due to insufficient optical confinement.
