In this work, we for the first time propose and demonstrate a feasible strategy for multi-band ultra-narrow optical transmission of the plasmonic crystals by introducing a high-index dielectric (HID) cavity, which can be acted as an efficient optical field coupling and hybridization component. Five sharp transmission bands with the maximal bandwidth of 6.5 nm are achieved. High spectral Q-factor of 327 with the corresponding bandwidth of 2.8 nm is observed in the optical region. These features pave a simple and universal way for multispectral narrowband optical transmission based on the typical plasmonic crystals. [ABSTRACT FROM AUTHOR]
