Abstract: The partially nonlocal multi-component nonlinear Schrödinger system is significant for modeling partially nonlocal nonlinear responses in multi-division multiplexing optical systems. This study addresses the limited research on three-component systems with distinct rogue wave configurations. We investigate a variable-coefficient 2D partially nonlocal three-component coupled nonlinear Schrödinger system with a linear potential, which we reduce to a constant-coefficient equation to facilitate analytical solutions. Using the Darboux transformation, we derive partially nonlocal dark-bright-dark rogue waves and their paired solutions. We further analyze their excitation regimes–complete, delaying, peak-sustaining, and inhibiting–by comparing the maximal accumulated time with their excited location values. These results enhance our understanding of ultrashort wave phenomena in physics and engineering.
