Abstract:Feedback-insensitive Quantum Dot (QD) comb lasers hold significant promise for integrated dense wavelength division multiplexing (DWDM) photonic systems due to their ability to generate multiple wavelengths and operate without bulky isolators, facilitating the development of high-density and large-scale photonic integrated circuits (PICs). In this study, we investigated the optical feedback (OFB) influence of InAs/GaAs QD comb laser from various perspectives. Our findings reveal that the comb laser exhibits a … Show more
