相位取样型光纤光栅多信道幅频与相频滤波性能研究的中期报告 Abstract: Thisreportpresentstheresearchprogressontheperformancestudyofamplitude-frequencyandphase-frequencyfilteringofmulti-channelfiberBragggratingsbasedonphasesampling.Thereportincludesabriefintroductiontotheresearchbackground,researchobjectives,researchmethods,andresearchprogress.Additionally,thereportsummarizestheresultsoftheamplitude-frequencyandphase-frequencyfilteringperformanceanalysis,anddiscussesthepotentialapplicationsoftheproposedmulti-channelfiberBragggratings. Introduction: FiberBragggratings(FBGs)areoneofthemostimportantopticaldevicesusedforvariousapplicationsincommunication,sensing,andmetrology.FBGscanbeusedaswavelengthfilters,dispersioncompensators,andsensingelements.OneofthemostimportantfeaturesofFBGsistheirabilitytoreflectlightwithacertainwavelength,makingthemapromisingtoolformulti-wavelengthsystemapplications.However,traditionalFBGscanonlyreflectlightinasinglewavelengthband,whichlimitstheirpotentialapplications.Toovercomethislimitation,multi-channelFBGshavebeenproposedandinvestigatedinrecentyears. Multi-channelFBGscanprovidemultiplereflectionbands,whichcanbeusedforwavelengthdivisionmultiplexing(WDM)applications.Amongdifferenttypesofmulti-channelFBGs,phasesamplingFBGshaveattractedalotofattentionduetotheiruniqueproperties.IntheseFBGs,thephaseofthereflectionspectrumissampledperiodicallyalongthegratingstructure,whichallowsthegenerationofmultiplereflectionbands.Additionally,phasesamplingFBGscanprovidehighreflectivityandlowcrosstalkbetweenthereflectionbands.Duetotheseuniqueproperties,phasesamplingFBGshavebeenwidelyinvestigatedforvariousapplications,suchasWDMsystems,fiberlasers,signalprocessing,andsensing.
