Abstract :
This paper presents a model of an optical transmitter module (driver & laser) which takes into account temperature, besides electrical and optical effects. MOSFET is an important component of the driver, temperature occurs in its different parameters such as carrier mobility. The vertical cavity surface emitting laser (VCSEL) is managed by equations of continuity which describe optical and electrical behaviour. The VCSEL parameters depend also on temperature. This is why a thermal model has been added for showing the thermal exchange between VCSEL and other connecting components. VHDL-AMS language allows to describe these different multi-technological phenomena: electrical, optical and thermal.
