P-doped and undoped quantum dot (QD) semiconductor optical amplifiers (SOA) are compared regarding their static and dynamic characteristics. The amplified spontaneous emission and gain curves are evaluated for p-doped and undoped devices exhibiting a gain per length of 10 dB/mm and 7 dB/mm, respectively. P-doped and undoped devices having 22 dB and 23.5 dB chip gain, respectively, were compared in...
