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).

► The effect similar to the EIT in atomic system is presented in the two optical resonators system. ► One theoretical model is provided for the all-optical analogue to EIT. ► The design has been investigated to obtain high quality factor resonant mode.
