The detailed analysis of rate equation roots of BH-laser diode using Volterra series

In this study, the rate equation analysis of a BH-laser diode was performed for output carrier density ( No) using the zero-degree solution of the Volterra series. The carrier rate equation of the laser diode was analyzed in terms of input carrier density ( Ni) and output carrier density modeling ( Ni − No) , with respect to the DC current ( Io). The polynomial root, which is obtained from the zero-degree solution ( No) and limit values of Io, was found. For the linear operation of the laser diode, the range of Io current was also determined using a linearization approach and the maximum value of No.
