Abstract

The linewidth broadening factor (LBF) of a quantum dot (Qdot) laser is theoretically investigated by analyzing the laser’s optical noise characteristics. It is found that the LBFs of Qdot lasers driven by the optical noise are typically smaller than those driven by the modulated current. This is attributed to the weaker fluctuations of carrier populations in the excited state and in the carrier reservoir when the Qdot
laser is optically perturbed. The small optical noise-driven LBF indicates that the quantum dot laser is attractive for developing narrow-linewidth optical sources.
