Integrated semiconductor laser-transmitter model for microwave-optoelectronic simulation based on transmission-line modelling

The transmission-line laser model is a powerful and flexible method to model various types of laser devices. An integrated laser transmitter model comprising the intrinsic laser, an electrical parasitics network and a passive matching network is proposed for microwave-optoelectronic simulation in the time domain. Transmission-line matrix stub lines and link lines are used to model the matching network and electrical parasitics. The passive matching network is based on monolithically integrated lumped elements. The effect of electrical parasitics has been taken into account when designing the matching network. Simulation results are in good agreement with those of commercial software. A microwave application of the integrated laser transmitter model is demonstrated in harmonic generation through gain switching
