摘要： A phase shifter includes an optical waveguide, a plurality of impurity regions and a plurality of electrodes. The optical waveguide receives an optical input signal and outputs an optical output signal. The impurity regions include respective charge carriers. The impurity regions are disposed in contact with the optical waveguide at respective contact surface, where at least one of the contact surfaces has a zigzag pattern. The electrodes are connected to the respective impurity regions. Application of an electrical signal to at least one of the electrodes phase-shifts the optical output signal with respect to the optical input signal. Therefore, the phase shifter may efficiently vary a magnitude of the phase shift of the optical output signal.
