“…On the other hand, in the coupled MCFs, several cores are placed to strongly and/or weakly couple between each other. Coupled MCFs supporting single transverse mode and multi transverse modes have been investigated for high power fiber laser applications [9,10], since they are able to be used as large-mode-area (LMA) fibers, while the coupled MCFs supporting a few supermodes can be used as few-mode fibers (FMFs) for large capacity transmission experiments with mode-division multiplexing (MDM) technique [11][12][13][14]. In terms of core arrangement in uncoupled MCFs, homogeneous MCFs with identical multiple cores [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] and heterogeneous MCFs with several kinds of different cores [31][32][33][34][35] have been reported.…”

Abstract:We experience Internet traffic growth of 100 times every 10 years. However, the capacity of existing standard single-mode fiber is approaching its fundamental limit regardless of significant realization of transmission technologies which allow for high spectral efficiencies. Space division multiplexing (SDM) based on multicore fibers (MCFs) has emerged as a solution to the problem of saturation of the capacity of optical transmission systems. This article presents the recent progress on the MCFs for future large capacity long-distance transmission systems. In MCFs, there is a tradeoff relationship between low crosstalk and high multiplicity, therefore the maximum number of cores and the core arrangement have to be carefully determined based on the required crosstalk level and core size. The state-of-the-art of fabricated MCFs and the transmission experiments using MCFs are reviewed. The current maximum capacity-distance product in MCF transmission is 368.2 (184.1+184.1) Pb/s/fiber km with the relative spatial efficiency of 4.7 compared with a standard single-mode fiber. In order to increase the spatial efficiency as well as the capacity-distance product further in MCFs, the possibility of heterogeneous MCFs and few-mode MCFs is also presented.

“…It offers new opportuni− ties for versatile operation and control of guided light. They have been widely applied to the sensing elements, spatial division multiplexing [3], microwave photonics [4], fibre lasers [5], amplifiers [6] and passive optical network [7], etc.. With the development of multi−core fibres, the cou− pled−power theory and the coupled−mode theory have been widely studied [8]. It can be also used to apply in couplers' manufacturing [9].…”

A novel wavelength selective coupler based on the all solid nine-core Ge-doped fibre has been proposed. The wavelength selective coupler is based on the phenomenon of a multi-core coupling. All the cores are made of Ge-doped silica and the index of central core is larger than the outer core. At the fixed fibre length, the different wavelength can be selected. The performances of coupling and propagation characteristics have been numerically investigated by using a full beam propagation method (BPM). Simulation results show that the all solid nine-core Ge-doped fibre can achieve simultaneous shorter coupler length and wideband filtering characteristics. The 0.763 mm and 0.745 mm wavelength selective coupler are proposed to achieve different wavelength division and the bandwidth is up to the 400 nm, and 300 nm, respectively.

“…Multicore optical fiber technology is also a powerful way for achieving novel optical components such as broadband directional couplers [3], narrow-band fiber filters [4], variable fiber attenuators [5], two-dimensional bending sensors [6], fiber lasers and amplifiers [7,8], and dispersion compensators [9]. For these applications, due to the rigid core/cladding physical structure, the fiber geometry is static, i.e., relative core-to-core movement is not possible.…”

We demonstrate the fabrication of a novel type of optical fibers with multiple parallel airsuspended cores by the sheet-stacking method. Using this technique we have constructed optical fibers with up to 10 parallel micron-size suspended cores. No extra scattering loss from the fabrication process was observed in a fabricated dual air-suspended core fiber. The sheetstacking method opens the way towards using a wide range of optical glasses for manufacturing multiple parallel suspended-core specialty optical fibers with novel optical functionalities such as dispersion tunability. Fusion splicing has also been successfully used to connect such a multiple core fiber with a conventional silica fiber.
