TLDR
In this paper, the sensitivity of single-mode quality to small variations in the fiber parameters and geometrical misalignments is studied in detail, and different methods are suggested to mitigate the mode quality degradation caused by errors in fiber parameters.Abstract:
Single-mode–multimode–multimode (SMm) fiber structure provides an all-fiber solution for exciting a single radial mode in a multimode fiber (MMF). The proposed SMm design essentially exploits the interfering modes of the first MMF for exciting a single mode in the second. In this paper, the sensitivity of single-mode quality to small variations in the fiber parameters and geometrical misalignments is studied in detail. Different methods are suggested to mitigate the mode quality degradation caused by errors in the fiber parameters. An estimate of the acceptable geometrical misalignments in the structure is also given for achieving a high-quality single mode from the device.read more

High-Speed Multimode Fiber Transmission by Using Mode-Field Matched Center-Launching Technique
TL;DR: In this paper, the authors proposed a mode-field matched center-launching technique by fusion-splicing a single-mode fiber (SMF) pigtailed transmitter to the MMF, where the splicing condition is optimized to expand the core of SMF slightly so that it can match the mode field distribution of the fundamental mode of MMF.
