“…Low-DMGD FMFs with parameters lower and higher than their optimum values can have LP modes with DMGDs with opposite signs, which makes possible the realization of DMGDcompensated links. A 4-LP-mode link with Max|DMGD| as low as 6 ps/km has recently been demonstrated [5]. Here, we have concatenated 6-LP-mode fibers with non-optimum core parameters (within the manufacturing tolerances) and we have found that links always had Max|DMGD| <25 ps/km.…”

We describe the design trade-offs that are at stake when optimizing few-mode fibers (FMFs) that support a high number (≥ 6) of LP modes. We particularly detail the design of 6-LPmode fibers that allow to multiply the capacity by a tenfold factor (two modes being spatially non-degenerate and four modes being two times spatially degenerate). For low-differential-mode-groupdelay (low-DMGD) FMFs adapted to strongly-coupled modedivision-multiplexed systems, trench-assisted graded-index-core profiles can be optimized to have Max|DMGD| <10 ps/km and undesired leaky LP modes appropriately cut off, while all guided LP modes show good robustness (Bend Losses <10 dB/turn at 10 mm bend radius). Such low-DMGD FMFs being sensitive to process variability, we show how fiber concatenations can efficiently compensate for this issue and that values <25 ps/km can realistically be reached. For weakly-coupled FMFs adapted to weakly-coupled mode-division-multiplexed systems, step-index-core profiles can be optimized to have large effective index differences, Δn eff , between the LP modes (Min|Δn eff | >1.0 × 10 −3 ) to limit mode coupling and A eff >∼100 μm 2 to limit intra-mode non-linearity with good mode robustness. For such weakly-coupled FMFs, sensitivity to process variability is small and main characteristics do not significantly change when variations are within the manufacturing tolerances. We also briefly discuss experimental validations.

“…DGD compensation works as long as along a single span, most of the light stays in the mode it was originally coupled in, and even if it can not reduce the effect of modal crosstalk, it will dramatically contain the spread of the MIMO impulse response. Based on DGD compensation transmission distances up to 1200 km [8] and 708 km [9] with 3 and 6 spatial modes, respectively were demonstrated.…”

“…Therefore, space-division multiplexing transmission with multi-core fiber and mode division multiplexing (MDM) transmission using few-mode fiber are currently attracting a lot of interest and being intensively studied because of their potential for improving transmission capacity [2]- [4]. Optical fiber and a mode multi/demultiplexer (MUX/DEMUX) are the key components for realizing and improving MDM transmission.…”

We propose a PLC-based mode multi/demultiplexer (MUX/DEMUX) for mode-division multiplexing. We show numerically that the PLC-based mode MUX/DEMUX with a uniform height on one chip can multi/demultiplex four modes (LP 01 , LP 11 a, LP 11 b, and LP 21 a) by using our proposed LP 11 mode rotator and a parallel waveguide. We successfully multi/demultiplex the four modes and achieve a relatively low-wavelength dependence over the C-band by using our fabricated four-mode MUX/DEMUX. Index Terms-Effective index, mode division multiplexing, mode multi/demultiplexer, PLC.
