Abstract
Example polarization processing optical devices, methods, and systems are disclosed. A polarization processing optical device includes a polarization beam splitter (PBS), a polarization rotator (PR), a coupler, and a phase tuner (PT), where one port of the PBS is configured to input a continuous light source, and the other two ports of the PBS are respectively connected to the PR and one port of the coupler, the PR is connected to another port of the coupler, the PT is disposed on a connection between the PBS and the coupler or a connection between the PR and the coupler, at least one port of the coupler is configured to output single-polarization light, and the PT is configured to control output optical power of the coupler.
