Entanglement plays a crucial role in the development of quantum-enabled devices. One significant objective is deterministic creation and distribution entangled states, achieved, for example, through mechanical oscillator interacting with confined electromagnetic fields. In this study, we explore cavity resonator containing two-sided perfect mirror. Although mirror separates modes into two independent fields, radiation pressure interaction gives rise to high-order effective interactions across all subsystems. Depending on chosen resonant conditions, which are also related position mirror, study 2n <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mn>2</mml:mn><mml:mi>n</mml:mi></mml:mrow></mml:math> -photon entanglement generation bilateral photon pair emission. Demonstrating non-classical nature oscillator, provide pathway control these phenomena, opening potential applications quantum technologies. Looking ahead, similar integrated devices could be used entangle subsystems vastly different energy scales, such as microwave optical photons.
