| contents | By breaking the symmetrical arrangement of double micro-ring resonator, the formation mechanism and performance of reflection and transmission spectrum and optical field distribution are investigated. The reflection spectrum is Fano shape. The Fano resonance has an asymmetric and sharp resonance peak can be independently tuned by changing the asymmetric coupling factor of the first micro-ring. The transmission spectrum is electromagnetically induced transparency(EIT)-like shape. The (EIT)-like resonance can be independently tuned by changing the absorption factor and the phase shift factor of the second micro-ring. The Fano and EIT-like resonance have low loss and high near-field localization characteristics, our research has promising applications in optical communication and opto-electronic modulators. |
