| 摘要 |
The application discloses a tunable optical filter (300) comprising a substrate (320), a tunable filter unit (330), a temperature control unit (340), and a housing (380). The substrate (320), the tunable filter unit (330) and the temperature control unit (340) are packaged inside the housing (380). The housing (380) comprises a light incident window (381) and a light exit window (382). The substrate (320) is disposed to be adjacent to the light incident window (381) or the light exit window (382), and used to support the tunable filter unit (330). The temperature control unit (340) is disposed on a surface of the tunable filter unit (330), and is used to adjust the channel wavelength of the tunable filter unit (330) by controlling the temperature. The light incident window (381), the tunable filter unit (330), and the light exit window (382) are aligned according to the optical path. The application also discloses an optical receiver assembly (700, 800, 900), an optical transceiver assembly (1100, 1300, 1500), and a multi-wavelength passive optical network system. |
