Abstract
In this paper , we measure the ultrafast gain and index dynamics of the QD ground state transition in p-doped electrically-pumped InGaAs QD optical amplifiers emitting near 1.3 mum at room temperature. A pump-probe differential transmission technique in heterodyne detection with sub-picosecond time resolution was used. The refractive index dynamics also showed noticeable differences between p-doped and undoped samples. From these data a transient and time-integrated linewidth enhancement factor has been deduced.
