Abstract

Traditional ring resonators can be manipulated through two factors: the coupling coeffi-cients and the optical roundtrip length. These two factors determine the most importantperformance parameters of the ring resonator such as the Q factor, the free spectralrange (FSR) and extinction ratio (ER). But there is another important factor that plays animportant role: the internal reflection(s). In this paper, we systematically discuss and ex-perimentally demonstrate our manipulation of reflections in silicon ring resonators by in-troducing one or two integrated tunable reflectors. Various applications and phenomenoncan be generated by these structures, including backscattering compensation, ultra wideFSR, Fano resonance and Electromagnetically induced transparency (EIT).
