| description | The utility model relates to the technical field of optical fiber communication, and provides a phase modulator, which comprises a substrate layer, and a buried metal layer, a lower cladding, a waveguide layer, an upper cladding and an upper electrode layer which are arranged on the substrate layer and are sequentially formed from bottom to top, the lower cladding, the waveguide layer and the upper cladding form an optical waveguide which is used for guiding transmission of an optical signal to be modulated; the buried metal layer and the upper electrode layer form a microstrip line and are used for transmitting a microwave signal for modulating the optical signal to be modulated; and the optical waveguide and the microstrip line are arranged in an overlapping manner. According to the phase modulator provided by the utility model, the modulation efficiency is improved, a lower half-wave voltage is obtained, the length of a device can be shortened, and the speed matching of a broadband modulation signal and an |
