Abstract :
In summary, our measurements clearly show, that the plasma effect in VCSELs has a significant impact on the FM tuning (amplitude and/or phase) starting at frequencies around 1 MHz. The second important result is that the laser FM tuning behaviour can not be modelled as a minimum phase system, i.e. the FM phase response or time step response can not be computed via Hilbert transform methods from only the FM amplitude response.
