From traditional rate equations,taking into account of the chip package parasitic parameters and the intrinsic area contacted parameters,a new equivalent circuit model of double hetero-junction semiconductor laser was proposed,and the effects of DC bias on the laser relaxation oscillation,small-signal frequency response and large-signal impulse response were analyzed with circuit simulation software PSpice.
