The noise behavior of optical devices plays a niche role in pursuing and realizing ultra-high efficient all-optical state-of-the-art applications. So, analyzing and enhancing relative intensity noise (RIN) has particular importance to all optical applications. This study utilized a self-consistent numerical calculation to investigate a 1300nm dot-in-a-well (DWELL) quantum-dot (QD) vertical-cavity surface-emitting laser (VCSEL) under optical injection locking (OIL). We investigated the impact of OIL and homogeneous broadening on the main operational characteristics of QD VCSEL, considering output power, optical gain, temperature, and carrier quantum efficiency. In addition, the noise behavior was comprehensively studied by calculating the RIN spectra and RIN response to injection current density. Furthermore, this paper discusses the necessary scrutinization of simulated characteristics in terms of phenomenology.
