Bandwidth of polymer optical fiber (POF) is severely limited in a few gigabits. In order to solve the toughest problem, a new type of POF, named hollow ring-core POF (HRC-POF) is designed and simulated. Compared with the SI-POF and GI-POF, the proposed HRC-POF can be used for supra-high bandwidth data transmission based on OAM-based space division multiplex. Compared with the reported glass-based hollow ring-core fiber, the HRC-POF provides a number of other advantages, such as low processing temperature, simple manufacturing process, and low cost. The simulated results show that a polystyrene-based HRC-POF can support 30 states (including 26 OAM ones) in the vicinity of 670 nm wavelength, which means that the HRC-POF can create a total of 30 channels for data transmission in POF communication. © 2019 Elsevier B.V.
