提出了具有PT对称性的金属-绝缘体-金属波导系统,由两个波导耦合一个环谐振器组成,环谐振器的上臂填充增益介质而下臂填充损耗介质.对表面等离激元在该系统的传输特性进行了研究,结果表明:通过平衡增益介质和损耗介质,PT对称性诱导的透明峰可以被清楚地看到,并且该透明峰具有反相位的特点.

We proposed a PT-symmetric metal-insulator-metal waveguide system,in which two waveguides coupled to a ring resonator,one arm of ring resonator was filled with gain medium,the other arm with loss medium.The transmission character of the system was studied.The results showed that,through balancing of gain and loss medium,PT-symmetry induced transparency can be clearly seen,which indicated the transmission peak have an opposite phases.
