Tóm tắt

Chúng tôi nghiên cứu việc sử dụng phi tuyến tự-Kerr và phi tuyến chéo-Kerr để thực hiện sự chặn photon mạnh trong một hệ thống quang cơ bốn mode được điều khiển yếu. Theo gần đúng Born—Oppenheimer, chúng tôi thu được sự liên kết tự-Kerr của khoang và sự liên kết chéo-Kerr giữa các khoang, tách biệt một cách adiabatic với dao động cơ. Bằng cách tối thiểu hóa hàm tương quan bậc hai, chúng tôi tìm ra điều kiện tham số tối ưu cho sự chặn photon phi truyền thống. Dưới điều kiện tối ưu, sự chặn photon mạnh có thể xuất hiện trong phi tuyến mạnh hoặc yếu.
