SPICE circuit models for semiconductor lasers with effects of carrier and lattice heating

Abstract

A SPICE circuit model for semiconductor lasers is developed to simultaneously incorporate the effects of the carrier and lattice heating. Numerical simulations for the dc, ac and transient responses of this circuit model are demonstrated. The circuit model is transformed from the rate equations that govern the dynamics of carrier density, photon density, electron temperature, hole temperature and lattice temperature in the active region of semiconductor lasers. SPICE codes are developed exactly according to this circuit model. This results from this work demonstrate the capabilities and versatilities of the SPICE circuits in simulating the complicated carrier and lattice heating processes for semiconductor lasers. The possibility of simulating optoelectronic systems in conjunction with electronic circuits and devices all by SPICE circuit models is also discussed.
