Abstract: A channel state information feedback method and an apparatus are provided, relate to the field of communications technologies, and are used to flexibly feed back channel state information, to implement balance between feedback overheads and feedback precision of the channel state information. The method-includes: includes sending a media access control (MAC) frame, where the MAC frame includes a processing mode bitmap, every n bits in the processing mode bitmap correspond to one feedback unit, and a value of the n bits is used to indicate a processing mode of channel state information of the corresponding feedback unit; and receiving a beamforming report, where the beamforming report includes one or more feedback fields, each feedback field corresponds to one feedback unit, the feedback field includes channel state information of the corresponding feedback unit, and the channel state information included in the feedback field is processed in a processing mode indicated by the processing mode bitmap.

Abstract: An embodiment of the present invention provides a photodetector chip, including a substrate, a semiconductor optical amplification section, and a photodetection section. The substrate includes a surface, the photodetection section and the semiconductor optical amplification section are arranged on the substrate, and the photodetection section is located in an optical signal output direction of the semiconductor optical amplification section. The semiconductor optical amplification section amplifies and filters an input optical signal to output an amplified and filtered optical signal to the photodetection section. The photodetection section is configured to convert the amplified and filtered optical signal into an electrical signal. The semiconductor optical amplification section includes a grating, the grating includes a first grating and a second grating that are cascaded, and the first grating is a slanted grating. The first grating and the second grating are configured to filter an optical signal entering the semiconductor optical amplification section.
