    Directly modulated laser spectrum explaination

    modulated laser spectrum Hi, Initially I've generated an unmodulated (power against frequency) spectrum, using a simulation software. Now, I'm trying to generate the spectrum of a directly modulated laser. This is done by changing the default values of the laser module LaserRateEqSM. The...
