Abstract
A polarimeter includes a Polarization Maintaining (PM) coupler with an input configured to receive input light and split the input light to a first output and a second output; a first PM fiber coupled to the first output; a second PM fiber coupled to the second output; a first polarization device coupled to the first PM fiber; a second polarization device coupled to the second PM fiber; and a plurality of detectors coupled to the first polarization device and the second polarization device, wherein outputs i, i, i, iare determined based on outputs of the plurality of detectors, the outputs i, i, i, iare linear projections of corresponding Stokes Parameters of the input light.
