A non-Markovian modeling of frequency upconversion via four-wave mixing schemes
M. Gabriela Boada G., Jose Morales E, Andrea Delgado
We present a non-Markovian quantum master equation tailored for optimizing of parametric upconversion via four-wave mixing (FWM) in nonlinear optical systems. Our approach nonperturbatively embeds the device environment interaction into a structured noise model, going beyond the standard Markovian and rotating-wave approximations (RWA). By constructing an equivalent dynamical model where FWM occur within a pseudo-modal structured environment, we preserve the observable device response while naturally incorporating thermalization effects induced by coherent driving. This formulation reveals the physical origins of decoherence without compromising the functional behavior of device operations. Furthermore, we reformulate phase-matching conditions within our non-Markovian framework, providing new tools for optimizing nonlinear device performance in regimes where thermal parameter drifts and coherent driven interactions compete. This is particularly relevant for integrated photonic and superconducting quantum platforms where structured environmental modes interact with driven systems over prolonged timescales. Our results emphasize the limitations of Markovian approximations in modeling sustained nonlinear interactions and offer a practical pathway to improving conversion efficiency and coherence retention under realistic operating conditions. These findings provide theoretical guidance for engineering quantum photonic devices in temperature-sensitive regimes, where precision modeling of noise and back-action is critical to performance.
