[34] A depolarized optical source has a beam combiner by which light in orthogonal polarization modes is combined together. The beam combines 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 combines. The polarizati on 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 combines. In a different embodiment, the combines uses a 3dB coupler to provide a dual output.</SDOAB > |
