我们提出了一种基于自耦合光波导（SCOW）的谐振腔，以产生类似于电磁感应透明（EIT）的光学谐振。类EIT效应是由SCOW谐振器固有的两个谐振路径之间的相干干涉形成的。对于级联SCOW谐振器来说，它们产生的频谱受到它们之间的相移的显着影响，类似EIT的峰值被平坦化或分裂为两种极端情况。我们还研究了无限阵列的SCOW谐振器的色散特性，并表明EIT子带中的色散关系和群指数可以通过SCOW谐振器之间的小相移而大大改变。
We propose a self-coupled optical waveguide (SCOW)-based resonator to generate an optical resonance analogous to electromagnetically induced transparency (EIT). The EIT-like effect is formed by the coherent interference between two resonance paths inherent to the SCOW resonator. For cascaded SCOW resonators, the spectrum they produce is significantly affected by the phase shift between them, with the EIT-like peak flattened or split as the two extreme cases. We also investigate the dispersion characteristics of an infinite array of SCOW resonators and show that the dispersion relation and group index in the EIT subband can be greatly changed by a small phase shift between the SCOW resonators.
