The modulation instability of an extended nonlinear Schrödinger equation was investigated. It was found that the odd-order higher dispersion [beta(3)] does not contribute to the modulation-instability frequency. The time derivative of the nonlinearity was included and shown to affect the instability. Finally, nonlinear retardation effects are shown to alter the results significantly.
