无序对准PT对称结构中光子传输与相关特性的影响

Photon Transport and Two-Photon Correlation in the Disordered Quasi-PT-Symmetric Systems

主要研究了结构无序对光子在由耦合波导阵列构成的准PT对称体系中的传输与相关特性的影响.结果表明,当在准PT对称体系中引入非对角无序之后,由于Anderson局域效应使光子主要聚束在中心波导附近,且相变点变小,并增强了这种非厄米体系的吸收增强透过现象.

The influence of the off-diagonal disorder on the photon transport and two-photon correlation properties had been studied in the quasi-PT-symmetric systems formed by coupled waveguide arrays. The re- sults show that, by introducing off-diagonal disorder into the PT-symmetrie systems, photons mainly bunch around the incident waveguides due to the Anderson localization effect. Furthermore, the value corresponding to the phase transition point decrease, and the loss enhanced transmission of such non-Hermitian system is fur- ther enhanced.
