PROJECT TITLE :
Tunable Electromagnetically Induced Transparency in Plasmonic System and Its Application in Nanosensor and Spectral Splitting
A compact structure is proposed to realize electromagnetically induced transparency (EIT) response, which consists of a facet-coupled cavity and a ring resonator. Novel structures and also the transmission characteristics are studied in several totally different situations. The plasmonic device will be used as a high-sensitivity refractive sensor with a sensitivity of 1200 nm/RIU. In addition, multi-EIT-like peaks appear in the first broadband spectrum by adding another facet-coupled cavity or ring resonator, and therefore the physical mechanism is presented. The system paves a brand new approach toward highly integrated optical circuits and networks, notably for nanosensor, spectral splitter, and nonlinear devices.
