Abstract In terahertz frequency region, we have investigated theoretically the correlation between spectra of a free photonic structure and that deposited on a metal for several models of metal. It was found that for quasi-normal incidence of p-polarized electromagnetic field the presence of metal generates narrow spectral wells in the middle of reflection windows existing in a free photonic crystal. Quite another manifestation of metal-resonator inter-influence takes place at incident angles exceeding the Brewster angle when reflection spikes coincide with modes of photonic crystal resonator and they are absent throughout the stopband areas. The effects are strongly depended on polarization, number of periods and angle of incidence.

与金属膜接触的光子谐振器中太赫兹电磁波的混合 Fano-SP 谐振吸收

摘要 在太赫兹频率范围内，我们从理论上研究了几种金属模型的自由光子结构光谱与沉积在金属上的光谱之间的相关性。发现对于 p 极化电磁场的准垂直入射，金属的存在会在自由光子晶体中存在的反射窗的中间产生窄谱阱。当反射尖峰与光子晶体谐振器的模式重合并且它们在整个阻带区域中不存在时，金属谐振器相互影响的另一种表现发生在超过布鲁斯特角的入射角处。影响很大程度上取决于极化、周期数和入射角。
