The chirp parameter of electroabsorption modulators (EAMs) with intrastep quantum wells (IQWs) based on the InGaAsP material system is investigated theoretically. The chirp parameter of the IQW EAM, calculated by using the Kramers-Kronig relation, shows a discontinuity at a low voltage due to the blue shift in transition energy. Once the red shift is initiated, the chirp of the IQW EAM is similar to that of the conventional quantum-well (QW) EAM. Comparison with the conventional QW EAM shows that the IQW EAM could still be operated under high optical power without the compromise in chirp and absorption loss.
