Analysis about the effect of an on-chip all-optical analogue to electromagnetically induced transparency in the two resonators system

One theoretical model is provided for the design of an on-chip all-optical analogue to electromagnetically induced transparency (EIT) in the two resonators system. The design parameters (the perimeter and the separation of the resonators), the side-coupling efficiency and the resonator loss of the system have been investigated. The analysis shows, properly designed, the system exhibits an EIT-like transmission spectrum: a narrow high quality factor resonant mode (the line-width is about 0.1 nm).
