Abstract This paper is motivated by polarization-multiplexed optical transmissions and the challenge of designing optimal modulation codes for the 2x2 MIMO fiber channel. This is a specific use case that diverges from the classical MIMO models as non-ergodicity and low-complexity are key. While rather simple from a fundamental viewpoint, the proposed optimal schemes appears to be geometrically pleasing as the second minimum distance turns out to be the object of interest and the associated vectors encode the basis of a regular tetrahedron in the affine space. More operationally, the newly developed polarization codes for single channel use achieve unit dB gains while keeping low implementation complexity.
