Abstract
A path-switchable dual polarization controller includes an input polarization beam splitter (PBS) switchably connected to either one of two optical controllers configured to tunably remix polarization components received from the PBS to obtain two target polarization components of input light. When one of the optical controllers requires a reset, PBS outputs are switched to the other optical controller, and the first optical controller is reset offline. The circuit may be used for polarization demultiplexing.
