  • Patent number: 12034486
    Abstract: A filter includes a first filter component coupled to a second filter component. The first filter component is configured to receive an optical signal, and filter the optical signal based on a first power difference of signals transmitted on a plurality of frequency bands in the optical signal, where the first power difference includes a difference caused by a first doped optical fiber. The second filter component is loaded with a first driving electrical signal used to control a frequency response of the second filter component. The second filter component is configured to filter, using the frequency response based on a second power difference of the signals transmitted on the plurality of frequency bands, an optical signal obtained after the filtering by the first filter component.

  • Publication number: 20230231642
    Abstract: This application provides a tunable optical add/drop multiplexer T-OADM. A beam adjustment apparatus changes an incident angle at which an incident beam is emitted onto an optical filter. After the optical filter splits the incident beam into a transmitted beam and a reflected beam, the beam adjustment apparatus further adjusts a transmission direction of the transmitted beam emergent from the optical filter and a transmission direction of the reflected beam emergent from the optical filter, so that the transmitted beam and the reflected beam are output to corresponding ports, so as to implement a flexible and controllable T-OADM apparatus. This application may be applied to the optical communication field, for example, may be used to implement add/drop multiplexing of tributary signals in an optical domain in fields such as a long-haul backbone and a metropolitan area network.
