“…In order to receive the signal properly in the receiver end, it is an absolute necessity to use MIMO processing, which compensates linear impairments like dispersion, crosstalk, and DGD between modes and polarizations [30], [33], [111]. MIMO systems are usually implemented with multiple equalizers followed by the DSP to clarify the signal and decide about the received symbols.…”

Single Mode Fiber's physical capacity boundaries will soon be reached, so alternative solutions are much needed to overcome the multiplying and remarkably large bandwidth requests. Space division multiplexing (SDM) using multicore fibers (MCF), multi-element fibers (MEF), multimode fibers (MMF) and their combination; fewmode multicore fibers (FM-MCF) or fibers based on orbital angular momentum (OAM), are considered to be the propitious stepping-stones to overcome the capacity crunch of conventional single-core fibers. We critically review research progress on SDM fibers and network components and we introduce two figures of merit (FoM) aiming in quantitative evaluation of technologies such as amplifiers, fanin/fan-out multiplexers, transmitters, switches, SDM nodes. Results show that SDM fibers achieve an 1185fold (18-fold) Spectral-Spatial Efficiency increase compared to the 276-SMF bundle (single-core fiber) currently installed on the ground. In addition, an analysis of crosstalk in MCFs shows how SDM concepts can be exploited further to fit in various optical networks, such as core, metro and especially future intra-datacenter optical interconnects. Finally, research challenges and future directions are discussed.reinforce diverse future optical network types, such as datacenters and metro/core networks, are demonstrated. Furthermore, we critically review other major networking aspects considering SDM network and node concepts and components, such as SDM Reconfigurable Optical Add/Drop Multiplexers (ROADMs), Self-homodyne detection and Multiple Input Multiple Output -Digital Signal Processing (MIMO-DSP) on SDM receivers, routing and core allocation complexity in MCFs as well as multidimensionality and granularity in switching. A study on the inter-core crosstalk interference constraint of MCFs for SDM networks is included. The outcomes of our analysis are specific MCF design rules considering the crosstalk vs fiber core-pitch relation and network link distance with regards to the end application; i.e. 10m to 1km for Intra-DC or tens to hundreds of kilometers for metro/core networks. Different network classes are examined in the light of the outcomes of this analysis, resulting in a complete report on the challenges and the role of SDM in future high-capacity scalable optical networks. Finally, section V discusses challenges, potential use-cases and future directions of SDM.

“…A potential new optical multiplexer scheme [6] was presented a few years ago by demonstrating the excitation of dedicated orbital angular momentum modes (OAMs) in ring core fiber by a mode multiplexer based on a planar optical phased array antenna. The antenna patches were realized as surface grating couplers [8] and fed by the output waveguides of an optical filter. The passive optical filter was in some aspects constructed as an arrayed waveguide grating (AWG) coupler.…”

Data transmission over multimode fibers has the potential to considerably increase the capacity limit of single‐mode fibers by exploiting the spatial dimension. For long‐haul systems, mode division multiplexing using one mode per channel in a few‐mode fiber requires coherent detection in conjunction with digital multiple input multiple output (MIMO) processing for signal separation. In the following we focus on spatial multiplexing using mode groups rather than spatial modes in standard graded‐index multimode fibers. In combination with on‐off keying (OOK) modulation and direct detection, these systems might be advantageous for access‐ and connection‐related applications, e.g., for super computer interconnects or in the near metro region at link lengths shorter than about 10 km. In this paper we study the potential of mode groups for mode group division multiplexing (MGDM). Single‐mode group transmission experiments at 10 Gb/s per mode group, experimental mode group launching by phase mask, and concepts for passive optical mode demultiplexers are discussed. © 2013 Alcatel‐Lucent.

Mode-division multiplexing (MDM) is widely researched, and we are researching mode converter by using multi-mode interference (MMI) waveguide. Wavelength division multiplexing (WDM) must be used in addition to the MDM, however, wavelength dependency exits for MMI in general as it works based on the interference of light. In this paper, we analyze the wavelength dependency of the MMI 0 th to 1 st mode-converter theoretically. As a result, we clarify the design scheme to suppress the wavelength dependency. Moreover, we show the sufficient performance of less than 1.0 dB in entire C-band for highly confined waveguide (Si/SiO 2 waveguide) as a design example.
