Abstract—In the paper, Coupled-resonator-induced-transparency(CRIT) phenomenon in a novel integrated on-chip opticalresonator system is experimentally demonstrated. The system iscomposed of a four-ring resonator with 20um diameter on silicon,whose spectrum has a narrow transparency peak with low groupvelocity. The CRIT effect is observed in the optical coupled-resonator due to the classical destructive interference. Thissystem can be used to study the slow and fast light experimentsbecause of its simplicity and flexibility. In this work, a CRITresonance with a quality factor of 7.2×104 is demonstrated withthe same cavity size and the power coupling of the system is 60%,which agree well with the theoretical analysis. The through anddrop transmission spectra of the resonator are coincided wellwith each other.
