How electrical modelling of semiconductor lasers can help to analyse complex photonic systems

In this paper, we present main results of electrical modelling of various semiconductor lasers specifying their advantages and drawbacks in terms of gain, noise, and non-linearity. As these components are considered as an electro-optical transducer in photonic-microwave links, their required characteristics and performances that cannot be unique and are strongly dependent on dedicated applications. Some sources must have a small linewidth for the generation of millimetre wave signals and others need high optical power and linearity. A focus on the modelled transducers is presented.
