Abstract
Embodiments of the present disclosure provide a multiplexer, and relate to the field of fiber communications technologies. The multiplexer according to the embodiments of the present disclosure includes a first light beam adjusting element, a second light beam adjusting element, a first light filtering and combining element, a second light filtering and combining element, a polarization changing element, and a light polarizing and combining element. The optical multiplexer according to the embodiments of the present disclosure may not only implement combining at least four light beams into one light beam but also reduce the number of reflection times of light during a light combination process.
Claims10
A multiplexer for combining light beams of different wavelengths into one light beam, comprising:
- a first light beam adjusting element configured to adjust propagation directions of a first light beam and a second light beam;
- a first light filtering arid combing element configured to combine a third light beam and the first light beam adjusted by the first light beam adjusting element to a fifth light beam,
- a second light filtering and combing element configured to combine a fourth light beam and the second light beam adjusted by the first light beam adjusting element to a sixth light beam,
- a polarization state changing element configured to change a polarization state of the sixth light beam to output a seventh light beam,
- a second light beam adjusting element configured to adjust a propagation direction of the fifth light beam or the seventh light beam;
- and
- a light polarizing and combing element configured to combine, after the propagation direction of the fifth light beam or the seventh light beam is adjusted by the second light beam adjusting element, the fifth light beam and the seventh light beam into one light beam,
