Optical multiple-input-multiple-output (MIMO) receiver using stokes vector measurements

An optical multiple-input-multiple-output (MIMO) receiver comprising:

• an input port configured to receive input light;
• a Stokes measurement apparatus configured to generate measurements of Stokes parameters;
• an optical MIMO demultiplexer configured to generate a plurality of demultiplexed output light signals based on (i) the input light and (ii) the measurements of the Stokes parameters generated by the Stokes measurement apparatus, wherein the optical MIMO demultiplexer is configured to receive an electrical signal from the Stokes measurement apparatus and phase-shift light in the optical MIMO demultiplexer based on the electrical signal;
• and
• a plurality of output ports configured to output the plurality of demultiplexed output light signals generated by the optical MIMO demultiplexer,
• wherein an analog bandwidth at which the Stokes measurement apparatus is configured to measure the Stokes parameters is smaller than an analog bandwidth of the demultiplexed output light signals, and
• wherein a bandwidth of the electrical signal received from the Stokes measurement apparatus is smaller than the analog bandwidth of the demultiplexed output light signals.
