    Abstract: The provided programmable photonic circuit includes a tunable optical coupler, an optical phase shifter, and a control unit. First and second waveguides are provided in a first section corresponding to each other in the tunable optical coupler, and the tunable optical coupler includes a first actuator to adjust optical coupling efficiency of an optical signal between the first and second waveguides. One waveguide of the first and second waveguides, and a perturbation waveguide are provided in a second section corresponding to each other in the optical phase shifter, and the optical phase shifter includes a second actuator to change the phase of an optical signal traveling through the one waveguide, by changing an effective refractive index of an optical mode of the one waveguide according to the gap between the one waveguide and the perturbation waveguide. The control unit controls driving signals applied to the first and second actuators.
