Based on the above discussion, the core diameter of the existing few-mode and multimode hollow-core fiber designs is still relatively large, and the loss of HCFs should be further reduced to
Multi-mode optical fiber has a core diameter that is much larger than the wavelength being carried. The large core allows for high numeric apertures for superior light gathering compared to single mode
A novel centro-symmetric nested antiresonant fiber (CNAF) design is proposed and investigated numerically for low-loss, multimode applications. Conventional single tube-lattice and nested
