PROBLEM TO BE SOLVED: To provide a circuit including an optical ring resonator circuit and a method relevant thereto.SOLUTION: The method includes a step of applying a voltage to an optical ring resonator circuit to adjust the resonant condition of a ring waveguide included in the optical ring resonator circuit. The method also includes the steps of: detecting the quantity of a current generated by the optical ring resonator circuit; and determining the resonant condition of the ring waveguide based on the quantity of the detected current.SELECTED DRAWING: Figure 4 |
