Abstract
This work investigates the radio-frequency (RF) linewidth characteristics of a single-section quantum dot self-mode-locked laser under a self-injection locking configuration to achieve a stable and compact on-chip pulsed light source. The results indicate an absence of chaotic oscillation and longitudinal mode broadening under the strongest optical feedback conditions. The quantum dot laser exhibits high tolerance to optical feedback, with significant RF linewidth compression, resulting in stable pulse generation. These findings suggest that singlesection quantum dot lasers are promising candidates for on-chip integrated pulsed light sources, offering new opportunities for applications in spectroscopy and quantum optics.
