So far, practical commercial telecommunication systems are almost entirely based on semiconductor-based lasers as their optical sources, because of their compact size, high speed and reliability, and direct electronic control.A monolithically integrated widely tunable narrow-linewidth light source was realized on an InP-based quantum dot (QD) gain material.

The quasi zero-dimensional nature of QDs and the resulting low linewidth enhancement factor enabled standalone distributed feedback (DFB) lasers with intrinsic linewidths as low as kHz.
