The ultra-high transmission of photonic nanojet induced modes in chains of core-shell microcylinders illuminated by a plane wave is reported. Using high resolution finite-difference time-domain simulation, the periodical focusing of lightwave in straight chains of touching core-shell microcylinders is characterized with the periodicity of photonic nanojets corresponding to the diameter of two microcylinders. The core-shell microcylinders are efficiently coupled to the collimated incident lightwaves. We observe the lightwave with high optical transport of 3 dB in the maxima of transmission spectra for a chain of core-shell microcylinders. The chains of core-shell microcylinders can be assembled inside hollow waveguide and used in a variety of microscopy techniques, biomedical applications, and optical microprobes with subwavelength spatial resolution.
