Paper Abstract

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.
