precisely the two partial current flows through r 3 and c 3 add up to a steep rising edge for the total current flow while undershoots in the current flowing through r 3 which are caused by inductive components are compensated by overshoots in the current flowing through c 3 the amplitudes and zero passages of the partial current flows in this case can be adjusted optimally through a careful selection of r 3 and c 3 fig6 b shows an expanded simulation which in addition to the current flows i ii through r 3 and c 3 also takes into account the time constants r 2 c 2 and r 4 c 4 with v and vi as additional compensation elements in the circuit arrangement according to fig5 so as to generate the total current iii which flows through the laser diode 2 by adding these additional compensation elements the rise time and pulse shape of the total current flow through the laser diode can be further improved as compared to the simulation in fig6 a without resulting in a worsening of the post oscillation behavior fig7 contains an additional exemplary embodiment of the circuit arrangement 1 according to the invention coinciding with the.
