Title：Multi-corestructurefiber,photoniccrystalfibercouplingandsensingcharacteristicsresearch
Background：
Withthedevelopmentofmoderncommunicationandtechnology,people'sdemandforhigh-speedcommunicationandhigh-qualitysensinghasbecomeincreasinglyurgent.Asanimportantmediumforinformationtransmission,opticalfibershavebeenwidelyusedinvariousfieldsduetotheiradvantagessuchaslargeinformationcapacityandlowtransmissionloss.Inrecentyears,multi-corestructurefibersandphotoniccrystalfibershaveemergedasnewtypesofopticalfibers,whichhavetheadvantagesofhighcapacity,highdensity,andstronglightconfinement.However,thecouplingandsensingcharacteristicsofthesefibersneedfurtherresearchandexploration.
Aim：
Theaimofthisresearchistostudythecouplingandsensingcharacteristicsofmulti-corestructurefibersandphotoniccrystalfibers.
