Characteristics of homogeneous multi-core fibers for SDM transmission
APL Photonics, 2019 We describe optical data transmission systems using homogeneous, single-mode, multi-core fibers (MCFs). We first briefly discuss space-division multiplexing (SDM) fibers, observing that no individual SDM fiber offers overwhelming advantages over bundles ...

Advanced Optical Materials, EarlyView.A new luminescence mechanism in Cs2NaInCl₆ is revealed through spontaneously formed In3+→In+ centers and Er3+/Yb3+/Sb3+ doping. Tunable visible, near‐infrared, downconversion, and upconversion emissions are demonstrated, while DFT calculations explain the electronic structure.
