The grating codirectional coupler and the reflective microring resonator are both formed on a silicon base. An anti-reflection film is disposed on a first end surface of the reflective SOA, and the first end surface is an end surface, coupled to a first waveguide of the grating codirectional coupler, of the reflective SOA. A second waveguide of the grating codirectional coupler is coupled to the first waveguide, a first grating is disposed on the first waveguide, a second grating disposed opposite to the first grating is disposed on the second waveguide, and the first grating and the second grating constitute a narrow-band pass filter.

摘要： A detection coil includes a first group of coils, a second group of coils, and a third group of coils that are continuously wound and coaxial, and the second group of coils is located between the first group of coils and the third group of coils. A coil that generates the first magnetic field is coaxial with the first group of coils, the second group of coils, and the third group of coils. A sum of the induced electromotive forces of the first group of coils, the second group of coils, and the third group of coils is zero. When a metal foreign matter exists, a sum of the induced electromotive forces of the first group of coils, the second group of coils, and the third group of coils is not zero.

摘要： A communications apparatus includes a phase correction unit, a first radio frequency channel, a first analog bridge, a second radio frequency channel, and a second analog bridge. A first signal is sent to a first input end using the first radio frequency channel, and is divided into at least two channels of first sub-signals by using the first analog bridge. The at least two channels of first sub-signals are respective output from at least two first output ends to at least two first antenna arrays. Similarly, a second signal is divided into at least two channels of second sub-signals by using the second analog bridge, and the at least two channels of second sub-signals are output to at least two second antenna arrays. A first channel of first sub-signal and a first channel of second sub-signal are coupled to the phase correction unit by using a coupler.
