Abstract

We theoretically discuss the interaction of electrons with LO phonons in quantum dot lasers using the coupled mode equations, and calculate lasing characteristics. The results show that there is no phonon bottleneck and an extremely low threshold current as well as a wide modulation bandwidth can be achieved.
