Opto-electro-thermal model of a VCSEL array using VHDL-AMS

In this paper, a new laser diode model is presented including electrical, thermal and optical behaviors. This kind of model is feasible due to the high potential of VHDL-AMS in mixed technology modeling. When simulating, quantities like current, voltage, dissipated thermal power, junction temperature, optic power and wavelength are calculated simultaneously. Interactions between these parameters are taking into account and equations are near physical laws. Simulation results show static and dynamic characteristics and temperature effects.
