Abstract

The characteristics of high-speed quantum well and quantum dot lasers are described. It is seen that substantial improvements in small-signal modulation bandwidth are obtained in both 1 micrometers (48 GHz) and 1.55 micrometers (26 GHz) by tunneling electrons directly into the lasing subband. In quantum dots the small-signal modulation bandwidth is limited by electron-hole scattering to approximately 7 GHz at room temperature and 23 GHz at 80 K.
