Vinit,
Could you provide more information on what you are trying to do? In past discussion with designers, they seem to separate the "optical" characteristics of the diode from the "electrical" characteristics. For example, correct modeling of the capacitance is critical because that effects the bandwidth of the Trans-Impedance Amplifier. However, the IC designers I have spoken with don't seem to care as much about the "optical" characteristics of the photo-diode. Are you actually trying to model the entire closed-loop system, for example, DVD head positioningg, in order to model the loop dynamics? Could you just use a table model to convert laser power into current?
Best Regards,
Sheldon
