Abstract：

Photon　blockades　are　traditionally　classified　into　conventional　and　unconventional　types,　depending　on　distinct　physical　mechanisms.　Regarding　the　cavity　decay　rate　κ,　the　conventional　photon　blockade　takes　place　under　strong　nonlinearity　condition　(g＞κ),　whereas　the　unconventional　photon　blockade　occurs　in　the　regime　of　weak　nonlinearity　(g＜κ).　We　here　propose　how　to　derive　an　optimal　condition　for　photon　blockade　utilizing　a　two-photon　Jaynes-Cummings　model.　Under　this　condition,　the　equal-time　second-order　correlation　function　reaches　its　minimum,　leading　to　photon　antibunching　in　both　conventional　and　unconventional　photon　blockade　regimes　(g＞κ　and　g＜κ),　even　in　g∼κ.　This　characteristic　is　termed　universal　photon　blockade.　By　comparing　it　with　the　conventional　and　the　unconventional　photon　blockades　in　the　weak-driving　limit,　the　advantages　of　universal　photon　blockade　are　revealed.　Our　proposal　paves　an　avenue　towards　the　future　study　of　photon　blockades　and　has　potential　applications　in　generating　antibunched　photons.　　©　2025　American　Physical　Society.
