    For mode vector modulation, used in conjunction with direct-detection, we present geometrically-optimized signal sets that correspond to the densest sphere packing in the generalized Stokes space. We show that the best trade-off between spectral and energy efficiency occurs for simplex constellations.

    Stokes vector modulation (SVM) can be used together with multimode and multicore fibers. We study various algorithms for optimal geometric constellation shaping and bit-to-symbol mapping in the generalized Stokesspace. We evaluate the performance of these constellations for optically-preamplified direct-detection receivers.

    We propose a new energy-efficient, short-haul, multidimensional modulation using spatial degrees of freedom in SDM fibers to create well-separated points in the generalized Stokes space. We study the transceiver architecture, geometric constellation shaping, bit-to-symbol mapping, and the performance of the optically-preamplified direct-detection receiver.
