“…For instance, in 2020, Fahad et al proposed a dual-guided PCF designed for high-capacity transmission, supporting quality OAM and LP modes [13]. Similarly, in 2022, Manxing et al presented a dual-guided modes ring-based photonic crystal fiber enabling the transmission of 170+62 OAM modes, while offering a large effective mode field area [14]. However, these cores of dual-ring fibers were constructed using the same material with same doping concentration, may resulting in mode coupling due to the closely aligned effective refractive indices of the vector modes in the inner and outer rings.…”

A dual-ring photonic crystal fiber (PCF) is proposed, which not only supports the stable transmission of orbital angular momentum (OAM) modes but also deftly mitigates interference of mode coupling between the two rings. This fiber design possesses two concentric ring-cores and claddings, each constructed from distinct materials, effectively functioning as independent OAM channels. Importantly, the absence of significant mode coupling between the OAM modes of the two ring-cores guarantees unhindered transmission of the dual rings. Remarkably, the outer ring can accommodate 82 OAM modes of transmission and the inner ring can accommodate 34 OAM modes of transmission. High mode quality (>94.13%) is observed for all OAM modes in both inner and outer rings at wavelengths from 1.5 to 1.6 µm. This special design ensures that the modes in the outer ring have excellent performance and also maintains the modes in the inner ring as unaffected by the outer ring to the greatest extent.
