摘要： A depolarized optical source has a beam combiner by which light in orthogonal polarization modes is comoined together. The beam combiner may be used in conjunction with a polarization maintaining 3dB splitter, into which is coupled light in both polarization modes that is divided by magnitude, allowing both polarization modes to be output along each of multiple output paths which are coupled, respectively, into multiple input paths of the beam combiner. The polarization modes along one of the output paths are inverted and phase decorrelated prior to being combined by the beam combiner. In another embodiment, a recirculation path is used with the polarization beam combiner. In a different embodiment, the combiner uses a 3dB coupler to provide a dual output.
