Abstract
We propose a design of a multi-OAM-modes ring-core fiber with two guided modes regions which possesses relatively large effective index separations required for the vector modes. This fiber can support 28 information states bearing OAM spanning 8 OAM orders with large effective mode area by using polarization multiplexing and both signs of topological charge in the ring region, combined with two degenerate fundamental polarization modes in the core region which can hold the whole C bands. There is a high isolation between the modes in these two regions. These designed features have potential applications in the next generation fiber communication systems either in the quantum domain or in the classical domain.
