Spatial modes have received substantial attention over the last decades and are used in optical communication applications. In fiber-optic communications, employed linearly polarized phase vortex carrying orbital angular momentum can be synthesized by fiber vector eigenmodes. To improve transmission capacity miniaturize system, straightforward eigenmode multiplexing generation of fiber-eigenmode-like polarization vortices (vector modes) using photonic integrated devices interest. Here, we...
The global quantum network requires the distribution of entangled states over long distances, with substantial advances already demonstrated using polarization. While Hilbert spaces higher dimensionality, e.g., spatial modes light, allow information capacity per photon, such mode entanglement transport custom multimode fiber and is limited by decoherence-induced coupling. Here, we circumvent this transporting multidimensional down conventional single-mode (SMF). By entangling spin-orbit...

In general, different types specialty fibers with ring-shape are preferred for more stable transmission, which, however, may face greater manufacturing challenge larger fiber loss compared to standard multi-mode (MMFs). Therefore, the deployed commercially available MMFs that can...
