三模系统二阶非线性诱导的非传统光子阻塞

Unconventional Photon Blockade Induced by Second-Order Nonlinearity in Three-Mode System

基于三模二阶非线性系统,推导一个Hamilton量.在双模驱动的条件下,先用该Hamilton量与常规非厄米Hamilton方法,得到发生非传统阻塞的最佳解析条件,再通过求解主方程的稳态解及二阶关联函数,得到发生阻塞的数值解.

A Hamiltonian of three-mode system was derived based on second-order non-linearity. Using this Hamiltonian and conventional non-Hermitian Hamiltonian method, we obtained the optimal analytical conditions for unconventional photon blockade under the condition of dual mode drive. And then, by solving the steady state solution of the master equation and second-order correlation function, we obtained the numerical solution for unconventional photon blockade.
