“…Multicore fibre for quantum communications Space division multiplexing (SDM) in optical fibre, i.e., communication through distinct and parallel cores/modes in multicore and few-modes fibres, will play a fundamental role in future classical communications, both for solving the future capacity crunch and for reducing the overall power budget, thus decreasing the total power consumption [25][26][27]. As reported in Figure 1 a), through SDM the achievable rate of an N-core MCF corresponds theoretically to N times the achievable rate of a single mode fibre [28].…”

During the last 20 years, the advance of communication technologies has generated multiple exciting applications. However, classical cryptography, commonly adopted to secure current communication systems, can be jeopardized by the advent of quantum computers. Quantum key distribution (QKD) is a promising technology aiming to solve such a security problem. Unfortunately, current implementations of QKD systems show relatively low key rates, demand low channel noise and use ad hoc devices. In this work, we picture how to overcome the rate limitation by using a 37-core fibre to generate 2.86 Mbit s −1 per core that can be space multiplexed into the highest secret key rate of 105.7 Mbit s −1 to date. We also demonstrate, with off-the-shelf equipment, the robustness of the system by co-propagating a classical signal at 370 Gbit s −1 , paving the way for a shared quantum and classical communication network. * dabac@fotonik.dtu.dk, bdali@fotonik.dtu.dk These authors contributed equally to this work 1 arXiv:1911.05360v1 [quant-ph] 13 Nov 2019 of integration with the bright signals used in classical communications [17][18][19][20][21][22][23]. In this work, we show how to overcome the low rate and compatibility limitations by exploiting a 37-core multicore fibre (MCF) as a technology for quantum communications [24]. This technology allows for efficient key generation, enabling the highest secret key rate presented to date. Moreover, we co-propagate in all the 37 cores simultaneously a high-speed classical signal, showing that the quantum communication is only weakly perturbed by it, paving the way for a full-fleshed implementation in current communication infrastructures.

“…In SDM, the signal power is distributed over multiple spatial channels in the form of multiple modes and/or cores, thus lowering the power density, hence decreasing the nonlinear distortions and allowing for increased capacity and reach. Recently, single-mode (SM)-MCFs containing more than 30 cores have been fabricated and tested in high capacity transmission experiments [5,6,7,8,9] and a few-mode (FM)-MCF containing 19 cores has been fabricated [10] with cladding diameters of less than 250 µm. However, because of a limited cladding diameter (CD) constraint of about 250 µm to ensure comparable mechanical reliability to that of SMFs [10,11], these number of cores are considered to be about the maximum ones that can be accommodated within a circular cladding cross section while keeping sufficient low inter-core crosstalk (XT) required for long-haul transmission systems.…”

“…Among the various forms of SDM, singlemode MCF transport offer some specific advantages and possibilities. For example, Pbit/s/fibre-class capacities and low-power optical transport networks are feasible using dense-SDM (DSDM) with a spatial multiplicity over 30 7,8 . In addition, the long-haul digital coherent transmission employed today over conventional single-mode fibre (SMF) can be fully supported using appropriate crosstalk (XT) management 9 .…”

1-Pb/s (32 SDM/46 WDM/768 Gb/s) C-band Dense SDM Transmission over 205.6-km of Single-mode Heterogeneous Multi-core Fiber using 96-Gbaud PDM-16QAM Channels

Abstract: We demonstrate the first 1-Pb/s unidirectional inline-amplified transmission over 205.6-km of single-mode 32-core fiber within C-band only. 96-Gbaud LDPC-coded PDM-16QAM channels with FEC redundancy of 12.75% realize high-aggregate spectral efficiency of 217.6 b/s/Hz.
