“…In contrast, in this contribution we analyse the modal properties of MC-MOF using an experimental approach. Furthermore, results presented in the literature shows that in order to obtain equal intensity distribution in each core the careful optimisation of the multicore fibre structure is needed [17,18]. We have shown that we were able to achieve the equal intensity distribution for our MC-MOF by coupled the light with a SMF-28.…”

“…These results indicate that the light from SMF-28 can effectively excite all cores of the MC-MOF without coupling a significant proportion of the input power to the cladding modes. It has been proven in the literature that is possible to achieve equal intensities in each core of 7-core MOF by careful optimisation of the fibre structure [17,18,20]. Each core is slightly different in practice due to manufacturing differences.…”

“…Large Mode Area (LMA) single-mode fiber, as a crucial optical transmission medium, plays a significant role in increasing the mode field area to effectively reduce laser power density while ensuring single-mode operation. It can substantially mitigate the impact of nonlinear effects, address transverse mode instability issues, and holds crucial significance in overcoming the development bottlenecks of high-power lasers [1][2][3][4][5]. To advance high-performance single-mode LMA fibers, innovative exploration of new LMA fiber types is urgently needed.…”

In this paper, we propose a novel type of hollow-core anti-resonance fiber (HC-ARF). The cladding region of this fiber is formed by a combination of nested tubes and U-shaped tubes, and the centrally symmetric arrangement significantly reduces sensitivity to polarization. The influence of parameters on the performance of the designed HC-ARF LMA is analyzed by a finite element algorithm. The simulation results demonstrate that the designed structure achieves a large mode area of 3180 µm2, bending loss of 2 × 10−2 dB/km, and confinement loss of 5 × 10−3 dB/km at a wavelength of 1064 nm. Similarly, at a wavelength of 1550 nm, the large mode area, bending loss, and confinement loss are 3180 µm2, 1.4 × 10−2 dB/km, and 4 × 10−2 dB/km, respectively. These results indicate unprecedentedly large mode areas and ultra-low losses compared to previous studies. Within the bending radius under consideration, the bending loss remains below 1.35 × 10−2 dB/km. Furthermore, by increasing the fiber radius, the large mode area can reach an extraordinary 6250 µm2. The proposed device exhibits excellent mode area and outstanding polarization insensitivity, along with favorable bending performance. We believe that the designed fiber holds promising applications in high-power miniaturized fiber lasers, fiber amplifiers, and various high-power fiber communication systems, and it can be applied in sensors that require polarization insensitivity and better bending performance.

“…Medjouri et al 24 simulated a Ge 15 Sb 15 S 70 photonic crystal fiber (PCF) with a large mode area of >200 μm 2 at 8 μm. Yi et al 25 numerically reported that a Ge 20 Sb 15 S 65 PCF with LMA of 1962 μm 2 could significantly reduce the nonlinear damage in the infrared spectrum. Ren et al 26 reported that a Ge‐As‐S/Ge‐As‐Se PCF with a core diameter of 91.2 μm has an LMA of 5200 μm 2 and an optical loss of >5.2 dB/m at 4.0 μm.…”

Large-mode area (LAM) fibers with high NA have been widely applied into thermal image, laser power delivery, and supercontinuum generation 1-4 due to their increased light coupling ability and enhanced power transmitting threshold. Additionally, their wider core can significantly reduce the impact of nonlinear effects in mid-infrared (MIR) laser transmission that would deteriorate their handing capability of laser delivery. 5,6 Moreover, LMA fibers can effectively restrain the amplified spontaneous emission in laser transmission. 7 Therefore, many laser delivery systems 8-10 need LAM fibers with high NA to increase the fiber power threshold. Currently, many glasses including silica, 11 fluoride, 12 and chalcogenide 13 are introduced to develop LAM fibers for mid-infrared high-power laser transmission. However, the silica-based fiber is disabled because of its strong fundamental vibration absorption in mid-infrared. For fluoride
