Abstract

The modulation characteristics of multi-section gain lever quantum dot lasers are investigated in this paper. A 20-dB enhancement in the amplitude modulation efficiency is observed in a two-section quantum dot laser. Based on rate equation analysis a novel modulation response equation is derived to describe the device dynamics. In addition the dependence of the modulation efficiency enhancement and 3-dB bandwidth on the length of the modulation section is discussed. A conservative estimate of the gain lever value of 33 is derived from the measured results.
