研究环间损耗和透过率对波导与双环侧向耦合系统的透射谱和相位谱特性的影响. 输入和输出关系通过传输矩阵来表示. 随着透过率的增加,透射谱都是类电磁感应透明型,透射谱和相位谱的形状发生了很大的变化. 随着环3损耗的增加,透射谱从类电磁感应透明线型变为洛仑兹线型. 此处的类电磁感应透明线型可以看成是由两个洛仑兹线型相干叠加而成的. 相位谱基本保持不变. 随着环2损耗的增加,透射谱都是类EIT型,透射谱和相位谱的形状基本保持不变.

The influences of loss and transmittance on the transmission spectrum and phase spectrum characteristic of waveguide and double-ring lateral coupling system are investigated in this paper.The input-output relationship is expressed by a transmission matrix.With the increasing of transmission,the transmission spectra are all EIT-like profiles ( electromagnetically-induced transparency, EIT ) .The shapes of transmission spectrum and phase spectrum make great change.With the increasing of loss of ring 3,the transmission spectrum change from EIT-like profiles to Lorentz profiles.The EIT-like transmission spectrum results from the interference between two Lorenz profiles.Phase spectrum is unchanged.With the increasing of loss of ring 2, transmission spectra are EIT-like profiles,the shapes of transmission spectrum and phase spectrum are unchanged.
