A reconfigurable coupled optical resonators in photonic circuits for photon shutting

We demonstrate a novel way to control the coupling rate in coupled ring resonators by controlling the relative position of the nanowires between the two cavities to modulate the resonance frequencies. A new system is presented and experimental results show that by tuning the coupling rate, the coupled ring resonators can be stimulated at the same time due to the same resonance frequency. This study will provide new ways to manipulate coupled photonic cavities in silicon photonic circuits and benefit the development of coupled optical cavities to achieve advanced functions.
