“…The performance of the fiber is affected by the diameter of air holes. 23 Although enlarged air-hole sizes can reduce the A eff and increase mode quality, they also lead to an increase in CD. The spacing of the air hole layers has little effect on the performance of the fiber and can be extended slightly to obtain better structural strength.…”

.Photonic crystal fibers (PCFs) have been extensively studied to enhance communication capacity and spectral efficiency by supporting orbital angular momentum (OAM) modes. However, the structural fragility resulting from the central air hole in PCFs undermines the fiber’s roundness. We introduce a hybrid PCF that replaces the central air hole with a material with a high refractive index. This innovation not only enhances the fiber’s structural strength but also introduces an additional communication channel. Furthermore, this method increases the amount of OAM modes supported for transmission in the ring. Numerical results demonstrate that significant differences in refractive indices exist between adjacent vector modes, with high mode quality (ranging from 74.6% to 97.6%) and a small effective mode area (ranging from 23.5 to 59.5 μm2). The proposed hybrid PCF can transmit 20 OAM modes in the inner core and 54 OAM modes in the outer ring. The spacing between the two layers of air holes has a minimal impact on the effective mode area and mode quality. However, the effective mode area decreases and the mode quality increases with the enlargement of the diameter of air holes. In addition, a decrease in doping concentration results in lower mode quality and a larger effective mode area. Moreover, the proposed hybrid PCF can be employed in OAM-based mode division multiplexing for high-capacity short-range fiber optic communication.

“…Silica-based optical fibers are widely employed in optical communication, medical procedures, and sensing due to their low attenuation at infrared (IR) telecom wavelengths [1][2][3]. A vital application scenario is their integration in severe environments distinguished by ionizing or non-ionizing radiation, for example, those encountered in fusion/fission-related facilities, high energy physics facilities, and space missions [4,5].…”

This article investigates the influence of temperature on the total ionizing dose (TID) effects in optical fibers.Radiation induced attenuation (RIA) spectra at 1310 nm were measured in G652, OM, PM1016-C, and homemade B1-R fibers during and after γ-irradiation at different temperatures. The B1-R fibers were doped with varying Al 2 O 3 content in their core and coating layers. Experimental results show that the B1-R fibers have significant lower losses compared with the other three fibers. At a temperature of 25° and a TID does of 50 kGy, the B1-R fiber showed an RIA of only 1.35 dB/Km, while the other three fibers exhibit a minimum loss exceeding 6.44 dB/Km. Furthermore, the B1-R fiber withstood an irradiation does 100 times higher than other optical fibers. For a fixed temperature, the attenuation in B1-R fibers recovered quickly after irradiation, reaching their minimum values approximately 15 days post-irradiation, whereas the other three optical fibers required more than 25 days to recover. This study also delves into the underlying mechanisms contributing to the radiation resistance of B1-R optical fibers. The findings presented in this work offer critical insights for the development of high-performance, radiation resistant fibers, rendering them suitable for deployment in challenging deep space environments characterized by intense radiation conditions.
