Photonic crystal fiber with double-layer rings for the transmission of orbital angular momentum
In this paper, we propose a novel photonic crystal fiber (PCF) with double-layer rings for transmitting orbital angular momentum (OAM). The substrate of PCF is a pure silicon base. The inner circle is doped with Fluoride to reduce the refractive index (RI), and the transmission domain is doped with...
